DEPENDENT SAMPLES: Using the same groups as above, the researcher continues the intervention for a second year and wants to know if the number of diagnoses varies between year 1 and year 2. Only the 6 families receiving the intervention are followed. The number of diagnoses for each family are recorded in the Table below. # of diagnoses in # of diagnoses Family Group year 1 in year 2 1 Diabetes education 10 6 Diabetes education 8 our W N Diabetes education 5 4 Diabetes education 4 Diabetes education 6 W / N Diabetes education 10 1. What is your null hypothesis for this research question? 2. Using an dependent samples t-test, calculate the observed t-statistic from the data above in Excel, Hint: You'll need to calculate the sum of differences and the sum of squared differences 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
