A national nursing organization is lobbying congress for funding to hire more nurses nationwide. One of
the arguments is that nurses, on average, work significantly longer than full time duty, assuming full
time is 40 hours per week. A sample of n = 9 nurses had the following work hours last week:
43, 45, 48, 41, 45, 50, 50, 53, 48
Do these data support their claim? (Use ? = 0.05, one-tail test)
29. Calculate the Sum of Squares (SS) of work hours for the sample.
30. Calculate the sample variance (s2) of work hours.
31. Calculate the estimated standard error (sM) of work hours for the sample.
32. Calculate the observed t statistic for the sample.
