average user spent about 75 minutes per day logged into their SlackBoard classes and that time spent ogged in is approximately normally distributed. A recent random sample of 72 accounts resulted in an average time of 100 logged in per day with a standard deviation of 41 minutes per day. Formulate and test a hypothesis to determine whether there is evidence to that there has been an increase n average individual use time per day. Conduct your test at a significance level of a = 0.01. Your nypotheses are: O Họ: µ = 75 Hg: p< 75 O Ho: µ = 75 Hg: p = 75 O Họ: µ = 0 H: p > 0 O Họ: µ = 75 H3: p > 75 What is the test statistic for this test? cest statistic = (Report answer accurate to 2 decimal places.) What is the p-value for this test? |(Report answer accurate to 4 decimal places.) o-value = The decision reached is O Fail to reject H, O Reject H, and accept H, As such, the final conclusion is that O There is significant evidence that suggests no increase in average usage. O There is not significant evidence to suggest an increased average usage time per user. O The usage times have not changed. O There is significant evidence to suggest an increased average usage time per user.
