INDEPENDENT SAMPLES: An exercise physiologist is interested in examining the effect of a diabetes education intervention (designed to teach parents about healthy eating and physical activity) on the number of diabetes diagnoses that occur within the following year in a sample of pre- diabetic children. A total of 12 families with pre-diabetic children are recruited. Six families were in the diabetes education group and 6 were in the control group. The number of diagnoses for each family are recorded in the Table below. # of diagnoses Family Group in year 1 1 Diabetes education 10 2 Diabetes education 8 3 Diabetes education 5 4 Diabetes education 4 5 Diabetes education 6 6 Diabetes education 10 7 Control 7 8 Control 8 9 Control 9 10 Control 6 1 1 Control 12 Control 1. What is your null hypothesis for this research question? 2. Using an independent samples t-test, calculate the observed t-statistic from the data above in Excel. Hint: You'll need to calculate the mean and sum of squares for each group. What is the critical t-value for this research question? Hint: Use the table of critical values and the degrees of freedom to locate this value. The alpha = 0.05. 4 . hypothesis? What can you conclude based on your data? Do you reject or fail to reject the null
