Question

A study of Osteoporosis in men with hyperpropactinemic hypogonadism reported the serum testosterone for 6 men before and after treatment with surgery. These testosterone levels are shown in the table below. Do the data provide evidence that the population testeosterone mean before treatment differs from the population testosterone mean after treatment? Use 0.05 significance level.

Pretreatment and post treatment serum testosterone (ng/dl) for men with hyperprolactinemic hypogonadism.

Patient #	Before Treatment	After Treatment
1	127	501
2	58	250
3	171	357
4	87	80
5	186	140
6	379	460

Answer 1

From the given information above,

The null and Alternative Hypothesis is ,

H0: μd = 0

H1: μd ≠ 0    (two-tailed)

The p value is greater than 0.05. We fail to reject the null hypothesis. THERE IS NOT SUFFICIENT EVIDENCE TO SUPPORT THE CLAIM
