Transcribed Image Text:A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use the critical-value approach.
Given:
- \( \bar{x} = 40.4 \)
- \( s = 5.9 \)
- \( n = 15 \)
- \( H_0: \mu = 32.6 \)
- \( H_a: \mu \neq 32.6 \)
- \( \alpha = 0.05 \)
Options:
**A.**
- Test statistic: \( t = 5.12 \)
- Critical values: \( t = \pm 1.96 \)
- Conclusion: Do not reject \( H_0: \mu = 32.6 \). There is not sufficient evidence to support the claim that the mean is different from 32.6.
**B.**
- Test statistic: \( t = 5.12 \)
- Critical values: \( t = \pm 2.145 \)
- Conclusion: Reject \( H_0: \mu = 32.6 \). There is sufficient evidence to support the claim that the mean is different from 32.6.
**C.**
- Test statistic: \( t = 5.12 \)
- Critical values: \( t = \pm 1.96 \)
- Conclusion: Reject \( H_0: \mu = 32.6 \). There is sufficient evidence to support the claim that the mean is different from 32.6.
**D.**
- Test statistic: \( t = 5.12 \)
- Critical values: \( t = \pm 2.145 \)
- Conclusion: Do not reject \( H_0: \mu = 32.6 \). There is not sufficient evidence to support the claim that the mean is different from 32.6.
