You may need to use the appropriate technology to answer this question. It is reported that the time married men with children spend on child care averages 6.5 hours per week. You belong to a professional group on family practices that would like to do its own study to determine if the time married men in your area spend on child care per week differs from the reported mean of 6.5 hours per week. A sample of 40 married couples will be used with the data collected showing the hours per week the husband spends on child care. The sample data are contained in the file Child Care. 7.3 6.5 8.2 5.8 9.0 7.2 9.4 7.5 5.4 8.0 9.4 7.6 8.3 9.8 9.0 6.2 4.7 O Ho: 26.5 H₂: μ< 6.5 7.7 5.8 3.6 9.7 6.2 8.7 10 Ho: H≤ 6.5 Ha: μ> 6.5 Ho: μ> 6.5 Hgi u 5 6.5 Ho: μ = 6.5 H₂: μ # 6.5 o Hou<6.5 H₂:μ ≥ 6.5 4.5 11.4 7.9 7.0 6.3 3.8 8.1 7.0 7.6 2.3 7.0 (b) What is the sample mean in hours per week? x hours per week 7.5 (a) What are the hypotheses if your group would like to determine if the population mean number of hours married men are spending in child care differs from the mean reported in your area? 0.6 11.2 0.6 7.9 8.3 What is the test statistic?
