Question:

8.5.18 Consider the data set
34 54 73 38 89 52 75 33 50 39 42 42
40 66 72 85 28 71
which is a random sample from a with an unknown mean p. Calculate the following.
(a) The sample size.
(b) The sample median,
(c) The sample mean.
(d) The sample standard deviation.
(e) The sample variance.
(f) The standard error of the sample mean.
(g) A one-sided 99% confidence interval that provides a lower bound for μ.
(h) Consider the hypothesis test H0: μ = 50 versus HA : μ ≠ 50. What bounds can you put on the p-value using Table III?
