The table shown with this question counts the number of calls that arrive at atelephone help desk during the hours of 1 to 3 p.m. on 5 weekdays. Thecompany uses the same number of employees to staff the center for each ofthese days. Test the null hypothesis that the calls are uniformly distributedover these days, agreeing with the staffing policy.(a) Find the degrees of freedom of x².(b) Find the expected number of calls on a Friday, if Ho holds.(c) Find the value of x² for testing Ho.(d) Find the p-value for testing Ho.(a) The number of degrees of freedom is 4.(b) The expected number of calls on a Friday if Ho holds is 195.(Type an integer or a decimal.)(c) The value of x² for testing Ho is(Round to three decimal places as needed.)MondayTuesdayWednesdayThursdayFriday# Calls2051902201801800

When people learn a new task, their performance usually improves when they are tested the next day, but only if they get 6 hours sleep (Sticckgold, et al., 2000). The following data demonstrate this phenomenon. The participants learned a visual discrimination task on one day. Half of the participants were allowed to have at least 6 hours of sleep and the other half were kept awake all night. 6 hours sleep No sleep n =14 n = 14 M = 72 M =65 SS = 932 SS = 706 Is there a significant difference between the two conditions? Use a two-tailed test with α = .01.

A researcher is interested in examining the effects of relaxation techniques on test performance. The researcher randomly selects thirty college students and randomly assigns them into two groups of fifteen each. One group receives training in several relaxation techniques and the second group receives no training. Each group is given a statistics test. The average score for the group that received the relaxation training was 75 (s² = 5) and the average for students who did not receive the relaxation training was 50 (s² = 8). (1) State the null and alternative hypotheses for this study (2) What is the dependent and independent variable for this study (3) What test statistic/hypothesis test would you select to determine if the means are significantly difference at the alpha .05 level? (4) What critical value would you use to make your decision to reject or retain the null hypothesis at alpha .05?
