Given the null and alternative hypotheses, sample means, sample sizes, and population standard deviations shown to the right, conduct a hypothesis HA H1- P2<0 test using an alpha level equal to 0.01. X1 = 142 X2= 129 Họ: H1 -H2=0 01= 15 02= 19 n1 = 45 n2 = 65 ..... Determine the rejection region for the test statistic z. Select the correct choice below and fill in the answer box to complete your choice. (Round to two decimal places as needed.) O A. z> O B. z< or z> O C. z< Calculate the value of the test statistic = (Round to two decimal places as needed.) Since the test statistic V in the rejection region, V the null hypothesis. There is V evidence to conclude that the mean of population 1 is less than the mean of population 2.
