The sample of laptops built after the new process revealed the following quality scores: 116 111 101 120 99 94 106 115 107 101 110 92 The manager would like to know whether the new process increased average quality scores, you are asked to conduct the following hypothesis test: HO: H s 100 Ha: H > 100 What is the corresponding z-statistic? (Round to two decimal places in the form of 0.00) 2.35 What is the corresponding p-value? (Round to two decimal places in the form of 0.00) 0.01 At a - 0.075. does the new process increase the average quality score? (Answer Yes or NO) YES
