6 You are interested in understanding how the racial composition of school districts affectteacher's salaries. To do so, you collect data from a random sample of schools across theUS.The following table includes descriptive statistics for 2 random variables:teacher_salary summarizes the salaries of school teachers in the district (measured inthousand dollars)share_nonwhite summarizes the share of students in the district that are not white.(measured as a share of total student population)samplestandarddeviation100.20samplemeanteacher salary 60share_nonwhite 0.55The sample covariance between teacher salary and the share of nonwhite students inthe county is -0.12Using this information and OLS, estimate the following simple linear regression model:teacher_salary = Bo + Bi share_nonwhite + uRound your answers to two decimals:

For the given data β0 = ?β1 = ?

It is believed that 11% of all Americans are left-handed. A college needs to know how many left-handed desks to place in the big lecture halls being constructed on its campus. In a random sample of 220 students from that college, whether or not a student was left-handed was recorded for each student. The college wants to know if the data provide enough evidence to show that students at this college have a higher percentage of left-handers than the general American population?
