A random sample of 18 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 α=0.01.

H0: μ=55 versus H1: μ≠55.

Round your answers for the values of t to three decimal places.
