Question
A random sample of 22 observations taken from a
population that is normally distributed produced a
sample mean of 58.5 and a standard deviation of
7.5.
Find the range for the p-value and the critical and
observed values of t for the following test of
hypothesis, using a = 0.01.
Ho:H
55 versus H1:µ # 55.
Round your answers for the values of t to three
decimal places.
