She believes that on weekends, women (Pop1) sleep more hours per night than men (Pop2). Both populations are assumed to be Normal Distributions with unknown but, unequal standard deviations. She decides to test her hypothesis about sleep habits of women (Pop1) and men (Pop2). She surveys a total of 32 women and 25 men about the mean number of hours she or he, sleeps on weekends. Table 2 below displays the results of that survey> Table 2 Sleep Habits on Women and Men on Weekends .

Pick the correct choice below: a) One Sample Normal Distribution b) One Sample t Distribution c) Differences of two means using z scores d) Differences of two means using t scores 36 What is the value of the mean for this sampling distribution in this example? 37 Compute the differences between the given sample means. 38 Write the formula for the Welch's T test. 39 In the Welch's test, what is the value of the Estimate of the Standard Error of the Differences of Between the Two Means?

Do NOT state the decision here. 44 If we use a = 1%, what is the value of the critical cutoff score(s)? 45 Using the critical score(s) for a = 1%, what is the Decision Rule? Do NOT state the decision here. 46 Evaluate Welch's T rest and use it as Computed T. 47 If we use a = 5%, what is our final decision? Reject Ho or Do NOT Reject Ho? 48 If we use a = 1%, what is our final decision?
