Given the null and alternative hypotheses, sample means, sample sizes, and population standard deviations shown to the right, conduct a hypothesis HA: H1- H2 > 0 test using an alpha level equal to 0.05. X1 = 134 x2 = 140 01 = 11 02 = 10 Ho: H1- H250 n1 = 65 n2 = 50 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 three decimal places as needed.) O A. 7> В. 7< O C. z< or z> Calculate the value of the test statistic. (Round to two decimal places as needed.) Since the test statistic in the rejection region, the null hypothesis. There is evidence to conclude that the mean of population 1 is greater than the mean of population 2.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
Make sure to do the rounding and double check the Answers please.
