A team of scientists are conducting research on the effect of word fonts used in road signs on accident rates. Across the population, there is an average of μ = 40 accidents per year due to unclear road sign fonts, with a standard deviation of σ = 10. The distribution is approximately normal. The team believes that certain fonts are difficult to read and may cause accidents, and it wants to implement a change to road sign fonts nationwide. The team is recommending a new font to replace the old fonts in road signs. After a series of studies, the team finds that the new font decreases accidents. However, the effect size is rather small (d = - 0.2). If the change to road sign fonts is implemented and there truly is an effect, it is expected that the new average rate of accidents will be: μ = 38 (i.e., hypothesized mean of the treatment group). In other words, this change should decrease accidents by 2, on average. [50 points total]
A.) Because implementing such large-scale changes is very costly, the government wants to be sure that the investment will be impactful. For a hypothesis test, they want the α-level to be small to minimize error. It is decided that α = 0.01, and a one-tailed test will be used. [50 points]
-What type of error is minimized by setting a stricter (smaller) α-level?
-With a one-tailed hypothesis test at α = 0.01, use the unit normal table to find the zscore that marks the critical region.
B.) A sample of n = 100 people are selected to go through a road trial with new fonts in the road signs. Again, the treatment is expected to decrease accidents by 2 on average. If the researchers use a one-tailed hypothesis test with α = 0.01, what is the power of the hypothesis test? [10 points]
C.)An external consultant is worried that there may not be enough power to detect such a small effect with such a small sample size. The consultant recommends that the researchers select a sample of n = 400 people instead. With this new sample size, and assuming a one-tailed hypothesis test with α = 0.01 again, what is the power of the hypothesis test?
D.)Based on your answers in 3(b) and 3(c), calculate the probability of making a Type II error in both cases and explain what the values mean.
E.) Explain how sample size influences power. Discuss what this means in terms of the conclusions you might make in hypothesis testing. (You can use your answers in 3(b) and 3(c) as an example.)

What is the greatest common factor of 12a and 9a2? 9 36 3a 12a2
Answer:
3a
Step-by-step explanation:
12a and 9a^2

In his book Chances: Risk and Odds in Everyday Life, James Burke states that there is a 72% chance a polygraph test (lie detector test) will catch a person who is, in fact, lying. Furthermore, there is approximately a 7% chance that the polygraph will falsely accuse someone of lying. (Round your answers to one decimal place.) (a) Suppose a person answers 90% of a long battery of questions truthfully. What percentage of the answers will the polygraph wrongly indicate are lies
Answer:
6.3%
Step-by-step explanation:
From the informationn we have available in this question, there is 7% chance that this polygraph would accuse someone falsely and a 72% chance that the polygraph would be correct in predicting a list.
Now if a person's answer is 90% correct,
The percentage that the polygraph would pick wrongly to be lies =
0.07 x 0.90 x 100
= 6.3%

Use the clues to find the mystery number. The mystery number is –
• 1,000 when rounded to the thousands place;
• 800 when rounded to the hundreds place; and
• 770 when rounded to the tens place.
Which of the following could be the mystery number?
• 741
775
765
> 779
K BACK
QL
===========================
Explanation:
If we rounded 741 to the nearest tens, then it would round to 740. But we want 770. So we cross this off the list.775 rounds to 780 when rounded to the nearest tens. This is crossed off as well.765 rounds to 770 when rounding to the nearest tens place, it also rounds to 800 when rounded to the nearest hundreds place. Finally, 765 rounds to 1000 when rounded to the thousands place. This shows why 765 is the answer. Other possible answers include {766, 767, 768, 769} if we're only allowed to deal with whole numbers. The number 779 rounds to 780 when rounding to the nearest tens place. So we cross this off the list.3 (x - 2) = 7 – (4 - x)
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x=92x=92
Decimal Form:
x=4.5x=4.5
Mixed Number Form:
x=412x=412
the answer is x = 9/2
explanation
3 (x - 2) = 7 – (4 - x)
apply the distributive law to 3(x - 2)
to get 3x - 6
simplify 7-(4-x)
3 + x
you now have
3x - 6 = x + 3
add 6 to both sides
-6+6=0 3 + 6 = 9
3x=x+9
subtract x from both sides
3x - x = 2x x - x = 0
2x = 9
divide both sides by 2
2x/2 = x 9/2
to get x = 9/2
Suppose that your boss must choose three employees in your office to attend a conference in Jamaica. Because all 17 of you want to go, he decides that the only fair way is to draw names out of a hat. What is the probability that you, Anna, and Kevin are chosen? Enter a fraction or round your answer to 4 decimal places, if necessary.
Answer:
[tex]P(You\ n\ Anna\ n\ Kevin) = \frac{1}{4913}[/tex]
Step-by-step explanation:
Given
[tex]Total\ Employees = 17[/tex]
[tex]To\ Select = 3[/tex]
Required
Determine the probability of selecting You, Anna and Kevin
Assuming the selection process is fair;
Each employee has a probability of;
[tex]Probability = \frac{1}{17}[/tex]
So:
[tex]P(You\ n\ Anna\ n\ Kevin) = P(You) * P(Anna) * P(Kevin)[/tex]
[tex]P(You\ n\ Anna\ n\ Kevin) = \frac{1}{17} * \frac{1}{17} * \frac{1}{17}[/tex]
[tex]P(You\ n\ Anna\ n\ Kevin) = \frac{1}{4913}[/tex]
The probability that you, Anna, and Kevin are chosen is [tex]1\div 4913[/tex]
Calculation of the probability:Since there is three employees in your office to attend a conference in Jamaica. And, Because all 17 of you want to go, he decides that the only fair way is to draw names out of a hat.
So, here the probability should be
