Answer:
If six people all shake hands with each other, how many hand shakes were made in total?
Publish your book. Become an author in 15 days. Get published.
I assume that no two people shake hands if they've already shaken them earlier, irrespective of who initiated it.
In that case Guest 1 will shake hands with 5 others (Guest 2 to 6)
Guest 2 will shake hands with 4 others (Remember she's already shaken hands with Guest 1).
Guest 3 will shake hands with 3 others (having already shaken hands with Guest 1 and 2)
and so on.....
We end up with 5+4+3+2+1 handshakes or 15 handshakes in all!

Answers
Answer: The level of significance, , is the probability of committing a Type I error, rejecting the null hypothesis when it is, in fact, true.
Step-by-step explanation:
The significance level, which is commonly designated as alpha (α) is defined the probability of rejecting the null hypothesis when it is in fact, true.
To determine statistical significance, a researcher is expected to calculate a p-value. The researcher can reject the null hypothesis if the p -value is less than α as established by the researcher.

5-11. A polymer is manufactured in a batch chemical process. Viscosity measurements are normally made on each batch, and long experience with the process has indicated that the variability in the process is fairly stable with 20. Fifteen batch viscosity measurements are given as follows: 724, 718, 776, 760, 745, 759, 795, 756, 742, 740, 761, 749, 739, 747, 742. A process change is made that involves switching the type of catalyst used in the process. Following the process change, eight batch viscosity measurements are taken: 735, 775, 729, 755, 783, 760, 738, 780. Assume that process variability is unaffected by the catalyst change. Find a 90% CI on the difference in mean batch viscosity resulting from the process change. What is the practical meaning of this interval
Answers
Step-by-step explanation:
Confidence interval = 90% = 0.90.
1 - 0.90 = 0.10
Mean of 15 batch:
724+718+776+760+745+759+795+756+742+740+761+749+739+747+742 = 11253/15
= 750.2
Mean of second batch:
735+775+729+755+783+760+738+780
= 6055/8
= 756.875
Sd = 20
Z-alpha/2 = 1.64
= (750.2-756.875)-1.64*√20²/15 + 20²/8
= -21.0348
(750.2-756.875)+1.64*√20²/15 + 20²/8
= 7.68
2. The upper limit of the interval is less than 10 so in conclusion the difference in mean batch viscosity is about 10 or less than 10

Mrs. Ross needs to buy dish soap. There are four differently sized containers. Sort the brands from least to the greatest unit price. Round each unit price to the nearest thousandth.
Answers
Answer: Spotless soap < Bright wash < Lemon bright < lot of suds
Step-by-step explanation:
Given that 8 oz of Lots of suds cost = $0.98
Then unit price of 1 lot of suds = 0.98/8 = $0.1225
Given that 12 oz of Bright wash cost = $1.29
Then unit price of 1 Bright wash = 1.29/12 = $0.1075
Given that 30 oz of Spotless soap cost = $3.14
Then unit price of 1 Spotless soap = 3.14/30 = $0.104666666667
Given that 32 oz of Lemon bright cost = $3.50Then unit price of 1 Lemon bright = 3.50/32 = $0.109375
We also need to round the values to the nearest thousandth means three digits after decimal
Then unit price of 1 lot of suds = $0.123
unit price of 1 Bright wash = $0.108
unit price of 1 Spotless soap = $0.105
unit price of 1 Lemon bright = $0.109
Now we can easily sort them
0.105 < 0.108 < 0.109 < 0.123
respective names in sorted order are:
Spotless soap < Bright wash < Lemon bright < lot of suds
Employment statistics in the US are often based on two nationwide monthly surveys: the Current Population Survey (CPS) and the Current Employment Statistics (CES) survey. The CPS samples approximately US households and collects the employment status, job type, and demographic information of each resident in the household. The CES survey samples non-farm businesses and government agencies and collects the number of payroll jobs, pay rates, and related information for each firm.
a. What is the population in the CPS survey?b. What is the population in the CES survey?
Answers
Complete Question
The complete question is shown on the first uploaded image
Answer:
The population in the CPS survey is
Total number of US households
The population in the CES survey is
Total number of nonfarm businesses and government agencies
Step-by-step explanation:
From the question we are told that
The number of US households sampled by CPS is 60 , 000
The number of nonfarm businesses and government agencies sampled by CES is 140,000
Generally population is defined as the universal set where the samples are drawn from
Hence the population of CPS survey is the total number of US households
And the population in the CES survey is the total number of nonfarm businesses and government agencies

Answers
Answer:
Symmetric
Step-by-step explanation:
In the stem and leaf plot above which represents the current sale prices of houses in dollars, we can observe the shape of the distribution seem like that of a bell shape. Most of the data values are concentrated towards the center compared to the concentration at both extremes.
This implies that most of the current sales price is centered close to the median price of roughly 49/50 dollars.
Therefore, the distribution of housing price can be described as roughly symmetric.

7.8y - 26.2
Step-by-step explanation:
Answer:
y=-0.15
Step-by-step explanation:
Subtract the 6.4y on the left by the 14.2y, you will get 7.8y. The reason why you subtract instead of add is because you always do the opposite when adding/subtracting from the other side of the equal sign. Next, add the 12.5 to the -13.7 so you get -1.2. The whole equation would be 7.8y=-1.2. Then divide by 7.8 on both sides so that you get y=-0.15. Hope this helps :)

g Programs submitted by programs in a computer science course are examined for syntax errors and logic errors. Suppose 36% of all programs have syntax errors, 47% have logic errors, and 56% have at least one of those two error types. (a) What is the probability a program contains both error types? (b) What is the probability a program contains neither error type? (c) What is the probability a program has logic errors, but not syntax errors? (d) What is the probability a program either has no syntax errors or has no logic errors?
Answers
Answer:
The answer is below
Step-by-step explanation:
Let S denote syntax errors and L denote logic errors.
Given that P(S) = 36% = 0.36, P(L) = 47% = 0.47, P(S ∪ L) = 56% = 0.56
a) The probability a program contains both error types = P(S ∩ L)
The probability that the programs contains only syntax error = P(S ∩ L') = P(S ∪ L) - P(L) = 56% - 47% = 9%
The probability that the programs contains only logic error = P(S' ∩ L) = P(S ∪ L) - P(S) = 56% - 36% = 20%
P(S ∩ L) = P(S ∪ L) - [P(S ∩ L') + P(S' ∩ L)] =56% - (9% + 20%) = 56% - 29% = 27%
b) Probability a program contains neither error type= P(S ∪ L)' = 1 - P(S ∪ L) = 1 - 0.56 = 0.44
c) The probability a program has logic errors, but not syntax errors = P(S' ∩ L) = P(S ∪ L) - P(S) = 56% - 36% = 20%
d) The probability a program either has no syntax errors or has no logic errors = P(S ∪ L)' = 1 - P(S ∪ L) = 1 - 0.56 = 0.44
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Programs with syntax errors ; n(S) = 36%
Programs with logic errors; n(L) = 47%
Programs with atleast one of the two errors = 56%
P(S) = 0.36 ; p(L) = 0.47
P(SnL) = x
P(S) only + p(L) only + p(SnL) = 0.56
P(S) only = 0.36 - x
P(L) only = 0.47 - x
P(SnL) = 0.36 - x + 0.47 - x + x = 0.56
0.83 - x = 0.56
x = 0.27
B) probability that program contains neither error :
1 - p(program contains atleast one of the two errors)
1 - 0.56 = 0.44
C) probability of logic error but no syntax error :
P(L) - p(SnL)
= 0.47 - 0.27
= 0.20
Nazim is buying rice. The supermarket sells 10 kg of basmati rice for $15.45. Today they have a ‘buy 3, get the 4th free’ offer. The wholesaler also offers 50 kg sacks of rice for $59.00. Based on price, which rice should Nazim buy?
Answers
Answer:
50 kg sacks of rice for $59.00.
Step-by-step explanation:
Lets do the math. First, I want to see how much 50 kg of of the first option costs.
$15.45 is worth 10kg.
$15.45*3=$46.35
Since the fourth on is free, the sum will stay the same.
$46.35+$15.45=$61.80.
50 kg of the first option is worth $61.80.
50 kg of the second option is worth $59.00.
$61.80 > $59.00.
So, the second option is cheaper and the better deal.
