Compute estimates of the main effects and the interactions.
a.
Is it possible to compute an error sum of squares? Explain.
Are any of the interactions among the larger effects? If so, which ones?
d. Assume that it is known from past experience that the additive model holds. Add the
sums of squares for the interactions, and use that result in place of an error sum of
squares to test the hypotheses that the main effects are equal to 0.

Brink studied the effect of postural change on cardiovascular reactivity for a sample of healthy white and African American men and women. Change in systolic blood pressure (SBP) from supine to standing position was used as the measure of cardiac reactivity in a sample of 842 adults. Supine measurement of blood pressure was taken after participants had lain on an examination table for 15 minutes. Blood pressure was measured five times every 2 minutes using a preset automated blood pressure monitor, and the five measurements were averaged. Participants then stood up, and an additional five measurements were made over another 10-minute period and then averaged.
Below is a table describing the characteristics of Brink’s sample.

She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily’s hand without seeing it and without touching it. Among 280 trials, the touch therapists were correct 123 times (based on data in “A Close Look at Therapeutic Touch,” Journal of the American Medical Association, Vol. 279, No. 13). a. Given that Emily used a coin toss to select either her right hand or her left hand, what pro- portion of correct responses would be expected if the touch therapists made random guesses? b.
