Help/FAQ @ Trimmier Victoria CHALLENGE ACTIVITY 6.3.1: Hypothesis test for a population mean. 416580.2670904.qx3zay7 Jump to level 1 A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of 15 centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of 64 bolts. The sample mean bolt length was 15.06 centimeters. The population standard deviation is known to be o = 0.25 centimeters. What is the test statistic z? Ex: 1.23 What is the p-value? Ex. 0.123 Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of a = 0.05?| Select v 2 3 4 Check Next Feedback? Instructor note: MATCHED-PAIR TESTING Matched-pair testing is when there are two groups and the person or thing in one group determines who/what will be in the second group. If testing views on marriage between husbands and wives, they must be selected from the same couples. The wife in one group means that the wife's husband must be in the other group. Another way that matched-pair testing occurs is when the same indi- viduals are used in both groups. For example, if the effectiveness of training was being measured, the same people would be tested before and after the training 83.F 7:43 PM Mostly cloudy W 8/12/2022
