Transcribed Image Text:Arandom sample of 17 observations taken from a
population that is normally distributed produced a
sample mean of 42.4 and a standard deviation of 8.
Find the range for the p-value and the critical and
observed values of t for each of the following tests
of hypotheses using, a = 0.01.
Use the t distribution table to find a range for the
p-value.
Round your answers for the values oft to three
decimal places.
