Question

Use a t-test to test the claim about the population mean ? at the given level of significance ? using the given sample statistics. Assume the population is normally distributed. Claim: ? ? 7800; ? = 0.05 Sample statistics: x? = 7600, s = 420, n = 24 What are the null and alternative hypotheses? A. H0: ? ? 7800 Ha: ? < 7800 B. H0: ? ? 7800 Ha: ? = 7800 C. H0: ? = 7800 Ha: ? ? 7800 D. H0: ? ? 7800 Ha: ? > 7800

          Use a t-test to test the claim about the population mean ? at the given level of significance ? using the given sample statistics. Assume the population is normally distributed.
Claim: ? ? 7800; ? = 0.05 Sample statistics: x? = 7600, s = 420, n = 24
What are the null and alternative hypotheses?
A. H0: ? ? 7800
Ha: ? < 7800
B. H0: ? ? 7800
Ha: ? = 7800
C. H0: ? = 7800
Ha: ? ? 7800
D. H0: ? ? 7800
Ha: ? > 7800

Use a t-test to test the claim about the population mean μ at the given level of significance α using the given sample statistics. Assume the population is normally distributed. Claim: μ ≥ 7800; α = 0.05 Sample statistics: x̄ = 7600, s = 420, n = 24 What are the null and alternative hypotheses? A. H0: μ ≥ 7800 Ha: μ < 7800 B. H0: μ ≠ 7800 Ha: μ = 7800 C. H0: μ = 7800 Ha: μ ≠ 7800 D. H0: μ ≤ 7800 Ha: μ > 7800
