According to Centers for Disease Control, 35.5 percent of American adults have high low-density lipoprotein (LDL) or bad
cholesterol levels.
You conduct a research about the LDL level in the Indianapolis Metropolitan Area (IMA). You select a random sample adults in
IMA. The sample binary data is shown in worksheet DATA24.
At a 5 percent level of significance, does the sample evidence persuade you that the LDL level in IMA higher than the national
rate?

You run a regression to analyze the relationship between the hourly earnings and years of schooling.
The data (worksheet DATA26) shows WAGE (hourly earnings) and EDUC (years of schooling).
x = EDUC
y = WAGE
Find the intercept and slope coefficients of the regression.
