Question

An investigator wants to test the claim that there is no difference of a new weight loss medication at reducing BMI. The following table represents the results of individuals enrolled. Assume normal approximation is acceptable. (α=1)

 

Pt Pre test BMI Post test BMI
a 30.5 36.5
b 32.8 28.3
c 35.6 28.2
d 34.7 27.9
e 30.1 28.5

1. Write out your null alternative hypotheses H0d=, Ha: µd≠ 

2. Calculate a t stat 

3. What is the t-crit=±?

4. P-value =

5. do you reject or fail to reject null hypthosis?

6. Construct a 99% confidence interval and provide an interpretation. Does your interval further support your decision in the hypothesis test above
