A random sample of 15 hourly wages for restaurant servers (including tips) was drawn from a normal population. The sample mean and sample standard deviation were $14.9 and $6.75 respectevely. Can we infer at the 5% significance level that the mean wage for restaurant servers (including tips) is greater than 12? Null and Alternative Hypothesis: HO: µ Decision Rule : Reject HO if tcal > citical value t = Test statistic: (t calculated) t = H1: µ Conclusion: HO. We can't infer at the 5% significance level that the mean wage for restaurant servers (including tips) is greater than 12.

A random sample of 15 hourly wages for restaurant servers (including tips) was drawn from a normal population. The sample mean
and sample standard deviation were $14.9 and $6.75 respectevely.
Can we infer at the 5% significance level that the mean wage for restaurant servers (including tips) is greater than 12?
Null and Alternative Hypothesis:
Decision Rule : Reject HO if tcal > citical value t =
Test statistic: (t calculated) t =
HO: H
H1: H
Conclusion:
HO. We can't infer at the 5% significance level that the mean wage for restaurant servers (including tips) is
greater than 12.
