It is well documented that cholesterol over 200 is a risk factor in developing heart disease for both men and women (www.livestronge.com, January 11, 2011). Younger men are known to have higher cholesterol levels than younger women; however, beyond the age of 55, women are more likely to have higher cholesterol levels. a recent college graduate working at a local blood lab has access to the cholesterol data of 50 men and 50 women in the 20 - 40 age...

s Question Help Media periodically discuss the issue of heights of winning presidential candidates and heights of their main opponents. The accompanying table lists the heights (cm) from several recent presidential elections. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value ofr. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Should we expect that there would be a correlation? Use a significance level of...

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...

You will start by considering the data set in the proj2-2.txt file on BlackBoard. The data set contains SEX (1=female; 2=male), PEFR in l/min and height in cm. 1. Make a scatter plot of PEFR versus height. 2. Fit the simple linear regression of PEFR on height. 3. What is the estimated slope (with CI) and the interpretation of this estimate. 4. What is the standard deviation around the line (with CI) and the interpretation of this estimate. 5. Estimate...
