Data was collected to explain an employee’s annual income raise (expressed in $’s) based on the employee’s rating (on a scale of 1-20) Based on the regression results, answer the following questions d) What is the standard error of the error term in the regression equation? e) Is the coefficient on the variable “rating” statistically significantly different than 0 at the 1% level of significance? How do you know? f) What is the predicted raise for someone with an 18 rating?

tly sunny A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOS) of major corporations. He has good reason to believe that the mean systolic blood pressure, u, of CEOs of major corporations is more than 132 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be 142 mm Hg and the standard deviation of the sample to be 18 mm Hg. Based on this information, complete the parts below. 144Hz (a) What are the null hypothesis Ho and the alternative hypothesis H, that should be used for the test? 0 Ho : u = 132 H₁ H32 (b) Suppose that the researcher decides not to reject the null hypothesis.
