Question 1 SlackBoard, a company producing a Learning Management System (LMS) would like to know whether the) 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 75 accounts resulted in an average time of 85 logged in.per day with a standard deviation of 64 minutes per day. Formulate and test a hypothesis to determine whether there is evidence to that there has been an increase in average individual use time per day. Conduct your test at a significance level of a 0.01. Your hypotheses are: Ho: = 75 Ha: p > 75 Ho: μ= 75 Ha: p< 75 Ho: μ= 75 Ha: pz 75 UHo: H = 0 Ha: p> 0 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 Reject Ho and accept Ha Fail to reject Ho As such, the final conclusion is that There is significant evidence that suggests no increase in average usage. There is not significant evidence to suggest an increased average usage time per user. The usage times have not changed. There is significant evidence to suggest an increased average usage time per user.

Question 1 SlackBoard, a company producing a Learning Management System (LMS) would like to know whether they heed 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 75 accounts resulted in an average tíme of 85 logged in.per day with a standard deviation of 64 minutes per day. Formulate and test a hypothesis to determine whether there is evidence to that there has been an increase in average individual use time per day. Conduct your test at a significance level of a = 0.01. Your hypotheses are: Ho: H = 75 Hạ: p > 75 Ho: p = 75 Hạ: P< 75 Ho: H = 75 Ha: P z 75 Họ: H = 0 Ha: H > 0 What is the test statistic for this test? test statistic = (Report answer accurate to 2 decimal places.) %3D What is the p-value for this test? p-value = (Report answer accurate to 4 decimal places.)
