A random sample of professional wrestlers was obtained, and the
annual salary (in dollars) for each was recorded. The summary
statistics were x = 45,500 and n = 17. Assume the distribution of
annual salary is normal with o = 8,500.
(a) Find a 90% confidence interval for the true mean annual
salary for all professional wrestlers (in dollars). (Round your
answers to four decimal places.)

(1 point) Suppose the relation between CEO’s annual salary in
thousands of dollars, salary, and the return on equity,
roe, measured as a percentage, is estimated to be: . Now,
suppose that salary is measured in hundreds of dollars, rather than
in thousands of dollars, say, salarhun. What will be the
OLS intercept and slope estimates in the regression of
salarhun on roe?
The new estimates will be equal to the original estimates
divided by 10.
The new estimates will...
