A random sample of 105 observations produced a sample mean of 32. Find the critical and observed values of z for the following test of hypothesis using α=0.1. The population standard deviation is known to be 9 and the population distribution is normal. H0: μ=28 versus H1: μ>28. Round your answers to two decimal places. zcritical = zobserved =
inment Chapter 09, Section 9.3, Problem 036a Your answer is partially correct. Try again. A random sample of 23 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 oft for the following test of hypothesis, using a =0.01. Ho: = 55 versus H: 55. Round your answers for the values of t to three decimal places....
