A random sample of 19 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 of tto three decimal places. а. Но: и 3 46 versus H1: µ < 46. i < p-value < i tcritical i tobserved -1.96 %3D b.
