Question:

A random sample of 14 observations taken from a population that is normally distributed produced a sample mean of 212.37 and a standard deviation of 16.35. Find the critical and observed values of t and the ranges for the p-value for each of the following tests of hypotheses, using α = .10.
a. H0: µ = 205 versus H1: µ ≠ 205
b. H0: µ = 205 versus H1: µ > 205
