A social scientist would like to analyze the relationship between educational attainment and salary. He collects the following sample data, where Education refers to years of higher education and Salary is the individual’s annual salary (in $1,000s):
Education 3 4 6 2 5 4 8 0
Salary 40 53 80 42 70 50 110 38 Data is in the spreadsheet.
Use the Regression tool in Data Analysis to find the regression output. Are Education and salary related at the .01 level of significance?
a. No. We reject H0 because the pvalue is less than the level of significance, so the two variables are not related.
b. Yes. We do not reject H0 because the pvalue is less than the level of significance, so the two variables are related.
c. No. We do not reject H0 because the pvalue is less than the level of significance, so the two variables are not related.
d. Yes. We reject H0 because the pvalue is less than the level of significance, so the two variables are related.

A mortgage specialist would like to analyze the average mortgage rates for Atlanta, Georgia. He collects data on the annual percentage rates APR In % for 30-year fixed loans as shown in the following table. If he is willing to assume that these rates are randomly drawn from a normally distributed population, can he conclude that the mean mortgage rate for the population exceeds 4.2%? Test the hypothesis at the 10% level of significance. (You may find it useful to...
