SlackBoard, a company producing a Learning Management System (LMS) would like to know whether they need to run additional servers due to increased use of its LMS. SlackBoard knows that, historically, the average user spent about 75 minutes per day logged into their SlackBoard classes and that time spent logged in is approximately normally distributed. A recent random sample of 64 accounts resulted in an average time of 91 logged in per day with a standard deviation of 66 minutes per day. Formulate and test a hypothesis to determine whether there is evidence to that there has been a change in average individual use time per day. Conduct your test at a significance level of a = 0.1. Your hypotheses are: O Ho: H = 0 Ha: H > 0 O'Ho: H = 75 Ha: H 75 What is the test statistic for this test? test statistic = (Report answer accurate to 2 decimal places.) What is the p-value for this test? p-value = (Report answer accurate to 4 decimal places.) The decision reached is O Fail to reject Ho Reject Ho and accept Ha As such, the final conclusion is that The usage times have not changed. There is significant evidence that suggests no change in average usage. There is significant evidence to suggest a changed average usage time per user. There is not significant evidence to suggest a changed average usage time per user
