A random sample of 27 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.

Use the t distribution table to find a range for the p-value.

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

Enter your answer; the range for the p-value, lower bound < p-value <Enter your answer; the range for the p-value, upper bound
