A national nursing Organization is lobbying Congress funding to her nurse is nationwide. One ofthe arguments is that nurses, on average, work significantly loner than full time duty, assuming full time is 40 hours per week. A sample of n = 9 nurses had the following work hours last were 43, 45, 48, 41, 45, 50, 50, 53, 48 Do these data support their claim? (Use a = 0.05, one-tail test) Determine the degrees of freedom. Determine the tcrit value.

Calculate the mean (M) length of work hours for the sample. Calculate the Sum of Squares (SS) of work hours for the sample. Calculate the sample variance (s2) of work hours. Calculate the estimated standard error (Sm) of work hours for the sample. Calculate the observed t statistic for the sample.
