G Test 4 E Question 6 of 25 (1 point) | Question Attempt: 1 of 1 Time Remaining: 3:40.16 ( Sierra 4 5 10 11 12 13 An electronics manufacturing process has historically had a mean completion time of > minutes. It is claimed that, due to improvements in the process, the mean completion time, I, is now less than / minutes. A random sample of 20 completion times using the new process is taken. The sample has a mean completion time of /1 minutes, with a standard deviation of 8 minutes. Assume that completion times using the new process are approximately normally distributed. At the 0.10 level of significance, can it be concluded that the population mean completion time using the new process is less than 75 minutes? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (IF necessary, consult a list of formulas.) (a) State the null hypothesis Ho and the alternative hypothesis H1. P Ho : 1 Y H :0 (b) Determine the type of test statistic to use. (Choose one) O-0 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) X ? (d) Find the p-value. (Round to three or more decimal places.) 0 (e) Can it be concluded that the mean completion time using the new process is less than /> minutes? OYes ONo Continue Submit Assignment
