4 Perform a test of hypothesis to determine whether the average TIQ is lower than the industry standard of 2.5 minutes (150 seconds). Using a significance level of a=0.05 STEP 1 Ho: M = 2.5 The average TIQ is lower than the industry Ha: M > 2.5 minutes is greater than the average TIQ industry STEP 2 Significance Level: 0.05 STEP 3 TAKE SAMPLE n=100 __ X = 114.6298 Standard deviation 159.8848 P -value: p(X>114.6298) / Ho is true) Step 4 p-value < alpha I reject my Ho p-value> alpha I can not reject Ho The probability of getting that sample is 3 % its 3/100, so that probability is less than our threshold of 0.05 we are going to reject it because we have evidence for the alternative.
5 I do think that the company should allocate more resources to improve the average TIQ because it an average of around 159. Perform a test of hypothesis to determine whether the average ST with service protocol PE is lower than with the PT protocol. Use a significance level of α=0.05. Step 1 Ho= 2.5 minutes is lower that the service time Ha= 2.5 minutes is higher than the service time Step 2 The significance level is 0.05 Step 3 Sample = n=100 X= the mean of the service time which is 131.8689 Standard deviation = 190.7031 P-value =0.00926259470346566
