Transcribed Image Text:Assume that you have a sample of \( n_1 = 6\), with the sample mean \(\overline{X}_1 = 49\), and a sample standard deviation of \( S_1 = 6\), and you have an independent sample of \( n_2 = 7\) from another population with a sample mean of \(\overline{X}_2 = 34\) and the sample standard deviation \( S_2 = 5\). Assuming the population variances are equal, at the 0.01 level of significance, is there evidence that \(\mu_1 > \mu_2\)?
---
Determine the hypotheses. Choose the correct answer below.
- A. \( H_0: \mu_1 \neq \mu_2 \)
\( H_1: \mu_1 = \mu_2 \)
- B. \( H_0: \mu_1 \le \mu_2 \)
\( H_1: \mu_1 > \mu_2 \) ✔️
- C. \( H_0: \mu_1 > \mu_2 \)
\( H_1: \mu_1 \le \mu_2 \)
- D. \( H_0: \mu_1 = \mu_2 \)
\( H_1: \mu_1 \neq \mu_2 \)
Find the test statistic.
\( t_{\text{STAT}} = \) ⬜ (Round to two decimal places as needed.)
Expert Solution

Step 1
We have given that
Sample mean (x̅1) = 49
Sample mean (x̅2) = 34
Sample size (n1) = 6
Sample size (n2) = 5
Standard deviations (s1) = 6
Standard deviations (s2) = 5
Significance level (α) = 0.01
The null and alternative hypothesis are
H0 : µ1 ≤ µ2
H1: µ1 > µ2
