Suppose a researcher believes that the average height of female
students in a large local high school is 140 cm. The researcher
wants to construct an interval that contains the true average
height of all female students in the local high school with a
certain prespecified probability. The researcher selects 36 female
students at random from the high school. The distribution of
heights is known to follow a normal distribution.
Suppose a researcher believes that the average height of female...

An exercise science major wants to try to use body weight to predict how much someone...
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...
