SCENARIO 3

: Ideally, the researchers would want to track the participants over time to see if their

blood pressure increases. Assume that the variable labeled 'followup' represents the systolic blood

pressure of the 99 participants borne by diabetic mothers measured 20 years after the original

measurement was taken. At the 1% significance level, test the hypothesis that the systolic blood pressure

of children born by diabetic mothers changed between time 1 ('diabetic') and time 2 ('followup').

1. Correct T Test -
2. Cohen's defect size

o A statement of the research hypothesis that clearly identifies the populations under

Consideration.

o The mean of the comparison and the sample size, mean, and standard deviation of each

Sample.

o A statement of the type of t test, type of hypothesis test (one-tailed or two-tailed) and the

significance level (a)

o The results of the analysis including the t score, degrees of freedom (df),

p-value, and the Cohen's d effect size written in the following format:

T (df) = t score

P = t score

Cohen's d = d value

o An overall statement of the research conclusion.
