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 I- - \" -- - - 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. 3. 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. What can you conclude based on your data? Do you reject or fail to reject the null hypothesis
