Question

A prominent sociologist wants to determine the sexual attitudes of women aged twenty-five to forty-five. The main question explored is whether heterosexual women in this age group feel satisfied with their partners' sexual performance. The sociologist interviews two hundred of her friends who belong to the target group. She also asks two hundred of her female colleagues at her college to complete and return the survey asking the key question. She gets seventy-eight completed surveys back from women in the target group. She finds that 75 percent of all the interviewees say that they are not satisfied with their partners' performance. She concludes that most heterosexual women aged twenty-five to forty-five aren't happy with the sexual performance of their partners.

Answer 1

Answer: Her hypothesis is absolutely wrong.

Explanation:

Now we need to get all the details regarding her survey.

SAMPLE SIZE : 400

TARGET GROUP :200

From target group:

COMPLETED FORMS : 78

That is 78/200 × 100%

Consequently, only 39% of her interviewees in her target group returns with their survey forms completed. This means that 61% of her target group cannot be put into the indices that would determine if her hypothesis is wrong or correct. Reason is, 61%(or 122 women) is too large a number to make assumptions for. They could be happy with the sexual performance of their partners or not.
