1. For each sample, state the sample size, mean, and standard deviation.
Sample A: 0.75, 1.38, 2.13, 2.45, 4.7
Sample B: 2.18, 3.5, 4.7, 5.63, 7.35
2. State Hypotheses in statistical format: a. H0: b. H1:
3. State Significance Level: Use significance level α = .05
4. State critical t (explain how it was found)
5. State decision rule
6. Calculate the test statistic (pooled t): You must first calculate pooled variance, then calculate t.
7. State Decision (Reject or do not reject H0)
8. State Conclusion (what does your decision indicate)

The null and alternate hypotheses are: H0 : μ1 = μ2 H1 : μ1 ≠ μ2 A random sample of 8 observations from Population 1 revealed a sample mean of 25 and sample deviation of 4.5. A random sample of 8 observations from Population 2 revealed a sample mean of 26 and sample standard deviation of 3.5. The underlying population standard deviations are unknown but are assumed to be equal. At the .05 significance level, is there a difference between...

for these questions I need help on just the questions on all of them where it says "what is the value of the sample test statistic?" 24.) The average annual miles driven per vehicle in the United States is 11.1 thousand miles, with σ ≈ 600 miles. Suppose that a random sample of 36 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.9thousand miles. Does this indicate that the average miles driven per...

8. A random sample of 25 college males was obtained and each was
asked to report their actual height and what they wished as their
ideal height. A 95% confidence interval for μd= average difference
between their ideal and actual heights was 0.8" to 2.2". Based on
this interval, which one of the null hypotheses below (versus a
two-sided alternative)can be rejected?
A. H0: μd= 0.5
B. H0: μd= 1.0
C. H0: μd= 1.5
D. H0: μd= 2.0

Q2) Independent-Samples t-Test (15 points total) Help with H, I, J, K, L please! In a research project, researchers collected demographic and health data from a sample of elderly residents in the community. To examine any possible gender differences in their sample, they want to see if the females and the males differ significantly on the education level (number of years of formal schooling). The researchers are not predicting any direction in the possible gender differences so the hypotheses should...

The price to earnings ratio (P/E) is an important tool in financial work. A random sample of 14 large U.S. banks (J. P. Morgan, Bank of America, and others) gave the following P/E ratios.† 24 16 22 14 12 13 17 22 15 19 23 13 11 18 The sample mean is x ≈ 17.1. Generally speaking, a low P/E ratio indicates a "value" or bargain stock. Suppose a recent copy of a magazine indicated that the P/E ratio of...
