Q1. Consider the population of adult female residents in Melbourne (or Jupiter if you prefer). Our focus is on the population mean height. Let height be called X. Assume we do not know (population standard deviation) or the population mean, u. We take a sample of adult female residents in Melbourne (n=100) and calculate the sample mean height as 70 cm and the sample standard deviation of 25. i) Test the null hypothesis that u=120, against the alternative...

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...
