Using the two-sample hypothesis test comparing old call time to new call time at a .05 level of significance, discuss the hypothesis test assumptions and tests used. provide the test statistic and p-value in your response. evaluate the results of the hypothesis test with the scenario. provide recommendations for the vice president. using new call time and coded quality, develop a prediction equation for new call time. evaluate the model and discuss the coefficient of determination, significance, and use the prediction equation to predict a call time if there is a defect. evaluate whether the new call time meets customer specification. as stated in a previous lesson, customers indicated they did not want a call time longer than 7.5 minutes. assume a standard deviation of 2 min is acceptable. is the call center now meeting the customer specifications
