Question

Suppose a hypertension trial is mounted and 18 participants are randomly assigned to one of the comparison treatments. Each participant takes the assigned medication and their systolic blood pressure (SBP) is recorded after 6 months on the assigned treatment. The data are presented in the table below. Compute the totals for each column (1pt).

	Standard Treatment	Placebo	New Treatment
	124	134	114
	111	143	117
	133	148	121
	125	142	124
	128	150	122
	115	160	128
Totals	736	877	726

1. Indicate the Between Groups Sums of Squares (SSB, 3pts).

1. 0.12
2. 396.19
3. 14262.81
4. 2377.19
5. Some other answer; indicate:

Answer 1

The statistical software output for this problem is:

Hence,

SSB = 2376.77

Closest answer is 2377.19. Hence,

Option D is correct.
