The sample mean and standard deviation from a random sample of 33 observations from a normal population were computed as x¯=34 and s = 8. Calculate the t statistic of the test required to determine whether there is enough evidence to infer at the 10% significance level that the population mean is greater than 30.

A random sample of 11 observations was taken from a normal population. The sample mean and standard deviation are xbar= 74.5 and s= 9. Can we infer at the 5% significance level that the population mean is greater than 70? I already found the test statistic (1.66) but I’m at a loss for how to find the p-value.

a A random sample of eight observations was taken from a normal population. The sample mean and standard deviation are x = 75 and s = 50. Can we infer at the 10% significance level that the population mean is less than 100? b Repeat part (a) assuming that you know that the population standard deviation is σ = 50. c Review parts (a) and (b). Explain why the test statistics differed.

From a random sample from normal population, we observed sample mean=84.5 and sample standard deviation=11.2, n = 16, H0: μ = 80, Ha: μ < 80. State your conclusion about H0 at significance level 0.01. Question 2 options: Test statistic: t = 1.61. P-value = 0.9356. Reject the null hypothesis. There is sufficient evidence to conclude that the mean is less than 80. The evidence against the null hypothesis is very strong. Test statistic: t = 1.61. P-value = 0.0644....
