QUESTION 9 A firm is studying the delivery times for two raw material suppliers. The firm is basically satisfied with its current supplier A but would like to compare its delivery time to that of a competitor (supplier B). If the delivery time of A is longer than that of the firm will began making raw material purchases from supplier B. The firm samples 10 deliveries from supplier A and 10 deliveries from supplier B Using the.01 level of significance,...

In the picture below, I have the output for the same two sets of data. I ran the hypothesis test and the confidence interval. If you had a choice to use one output or the other, which would you choose and why? Make sure to be specific and include what information you get from each and what information you don't get if you use one over the other. Options Two sample T summary hypothesis test: : Mean of Population 1...

a) An engineer wishes to compare the mean lifetimes of two types of transistors in an application involving high-temperature performance. A random sample of 30 transistors of type A and a random sample of 30 oftype B were tested and the lifetime (minutes) of each transistor recorded. Appropriate plots and Minitab output are given below. Write a short report on whether there is evidence of a significant difference in the mean lifetime between the two transistor types [20 marks Descriptive...
