L2 A College S Job Placement Ofce Collected Data About Students Eras And The Sal
/in Uncategorized /by developerA college’s job placement office collected data about students’ GPAs and the salaries they earned in their first job after graduation. The mean GPA was 2.9 with a standard deviation of 0.3. Starting salaries had a mean of $48,000 with a SD of $8,100. The correlation between the two variables was r = 0.7. The association appears to be linear in the scatterplot.
(A) Write equation for the regression model that can predict starting salary based on GPA.
(B) Interpret the slope of the regression line in the context of this problem (in terms of the pertinent variables)
(C) Use this model to predict an estimate of a recent graduate’s salary whose GPA was 3.5.
(D) Calculate the coefficient of determination (R2) and interpret its meaning.

Consider the following combinatorial identity: H HE: _ n—lk=1 (:1) Present a combinatorial argument for this identity by considering a set of :1 people and determining, in two ways,the number of possible selections of a committee of any size and a chairperson for the committee.Hint: (i) How many possible selections are there of a commit-tee of size k and its chairperson? (ii) How many possible selections are there of a chair-person and the other conunittee members?
