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) 26. Determine the degrees of freedom. 27. Determine the tcrit value. 28. Calculate the mean (M) length of work hours for the sample. 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.33. Construct a 95% confidence interval to estimate the mean number of hours worked for the populations of nurses. What is the lower limit of this confidence interval? 34. What conclusion can be made from these data?
