Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses pst6wght-prewght. (12 points)
1. Set-up the hypotheses and significance level (2 points) 2. Set-up the decision rule (1 point) 3. Compute the test statistic using Excel (the test statistic is in your Excel output.) (5 points) 4. Give your conclusion. This must include either a comparison of the p-value to alpha or a comparison of the test statistic to the critical value. You also must explain what this result means.
