Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Use either the traditional method or P-value method as indicated. Identify the null and alternative hypotheses, test statistic, critical value(s) or P-value (or range of P-values) as appropriate, and state the final conclusion that addresses the original claim. Choose the correct option based on the problem information.
A large software company gives job applicants a test of programming ability and the mean for that test has been 160 in the past. Twenty-five job applicants are randomly selected from one large university and they produce a mean score and standard deviation of 183 and 12, respectively. Use a 0.05 level of significance to test the claim that this sample comes from a population with a mean score greater than 160. Use the P-value method of testing hypotheses. Choose the correct P-value and conclusion based on the null hypothesis.
A. P-value < 0.005. Fail to reject H0.
B. 0.01 < P-value < 0.025. Reject H0.
C. P-value < 0.005. Reject H0.
D. P-value = 0.05. Reject H0.
Answer:
C
explanation:
if The P-Value is low reject H0
The correct P-value and conclusion based on the null hypothesis. The correct option is C. P-value < 0.005. Reject H₀.
In this problem, we will use the P-value method to test a claim about the mean score of job applicants in a programming test. The claim is whether the sample of 25 job applicants from a large university comes from a population with a mean score greater than 160, given that the population is normally distributed. We'll use a significance level of 0.05 to make our decision. We'll set up the null and alternative hypotheses, calculate the test statistic, and find the P-value to draw a conclusion about the claim.
Let's begin by defining the null and alternative hypotheses:
- Null Hypothesis (H₀): The mean score of job applicants from the university is not greater than 160. H₀: μ ≤ 160.
- Alternative Hypothesis (H₁): The mean score of job applicants from the university is greater than 160. H₁: μ > 160.
Here, μ represents the true population mean score.
Next, we'll calculate the test statistic. Since the population standard deviation (σ) is not known, we'll use the sample's standard deviation (s) and perform a one-sample t-test. The formula for the t-test is:
t = (x' - μ₀) / (s/√n)
Where:
x' is the sample mean,
μ₀ is the hypothesized population mean under the null hypothesis (μ₀ = 160 in this case),
s is the sample standard deviation, and
n is the sample size.
Substituting the given values:
x' = 183 (sample mean)
μ₀ = 160 (hypothesized population mean under H0)
s = 12 (sample standard deviation)
n = 25 (sample size)
t = (183 - 160) / (12/√25)
= 23 / 2.4
≈ 9.583
Now, we need to find the P-value corresponding to this test statistic. Since this is a one-tailed test (claiming that the mean is greater than 160), we look for the area under the t-distribution curve to the right of t = 9.583.
By consulting a t-table or using statistical software, we find that the P-value is significantly less than 0.001. The exact P-value is not provided in the answer options, but it's crucial to note that it is well below 0.005.
Now, we compare the P-value to the significance level (α = 0.05). Since the P-value < α, we reject the null hypothesis (H₀). The data provides strong evidence to support the claim that the mean score of job applicants from the university is greater than 160.
The correct option is C. P-value < 0.005. Reject H₀. The statistical analysis indicates that there is strong evidence to support the claim that the mean score of job applicants from the university is greater than 160.

Use an equation to find the total number of buckets Alice delivers.
Answer:
120 buckets

Using it's concept, considering a spinner with four sections and a die with 6 numbers, there is a [tex]\frac{1}{6}[/tex] probability of landing on red and rolling a number greater than 2.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
The spinner has 4 sections, one of which is red, hence P(A) = 1/4.The die has 6 numbers, four of which are greater than two, hence P(B) = 4/6.The events are independent, hence:
[tex]P(A \cap B) = P(A)P(B) = \frac{1}{4} \times \frac{4}{6} = \frac{1}{6}[/tex]

What is the slope of a line that passes through the points (5,-3) and (13, -9)
Step-by-step explanation:
the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to the other.
so, we see
x changes by +8 (from 5 to 13).
y changes by -6 (from -3 to -9).
so, the slope is -6/+8 = -3/4
Hello.
Let's find the slope using the slope formula:
[tex]\mathrm{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]
[tex]\mathrm{\displaystyle\frac{-9-(-3)}{13-5} }[/tex]
[tex]\mathrm{\displaystyle\frac{-9+3}{13-5} }[/tex]
[tex]\mathrm{\displaystyle\frac{-6}{8} }[/tex]

none of these
Answer: none of these
Step-by-step explanation:
They are not supplementary because 101+77 = 178 and not 180.
They are not complementary because 101+77 = 178 and not 90.
They are not vertical because there are no intersecting lines and the two angle measures are not equal.
Therefore, none of these are true.

Answer:
No.
Step-by-step explanation:
First, we need to firgure out what 1/4 of 18 is (4.5). Then, multiply 4.5*22 to see the gallons left by the average traveled each gallon (99). Clearly, 99 is not equal to or greater than 110.
Find angle measure x on each given figure. (Lessons 9.2, 9.4, 9.5)
1. x = 60 (in this trapezoid, opposite angles are equal)
2. Find the third angle of the left triangle : 180 - 17 - 133 = 30
In a parallelogram, the side that is opposite to a side is parallel to each other.
x and the 30 degree are alternate angles -> x = 30
3. (I'll call the 4 triangles A,B,C,D respectively in anticlockwise)
Triangle A has the 25 degree angle, and the bottom right angle of triangle C, they are alternate angles (and the sides are parallel due to the property.)
So, the bottom right angle of triangle C = 25
Triangle C and D form an isoceles triangle, so x = 25.
4. This one I'll just do short. There's a right angle in the triangle that contains x.
3 angles in a triangle add up to 180, so x = 180 - 90 - 50 = 40.
The equation for line p can be written as y= – 5/4 x–6. Line q includes the point (5, – 8) and is parallel to line p. What is the equation of line q?
Answer:
y = -(5/4)x - (1 3/4)
Step-by-step explanation:
A line parallel to y= -(5/4)x - 6 will have the same slope, -(5/4), but a different value for the y-intercept, which is -6 in this equation. This means we can write:
y = -(5/4)x + b
As klong a b is not -6, the line will be parallel. But we are told that point (5,-8) must be on the new line. That means we need to select a value of b to make that happen. By shifting b, we can move the straight line up or down. To move it so that it goes through (5,8), enter that point in the equation and solve for b:
y = -(5/4)x + b
-8 = -(5/4)*5 + b for (5,-8)
-8 = -(25/4) + b
b = -8 + (25/4)
b = -(32/4)+(25/4)
b = -(7/4) or - 1 3/4
The parallel line that goes through (5,-8) is y = -(5/4)x - 2

y=-5/4x-7/4
