Question #2023037: Testing Statistical Hypothesis


Question: This question consists of two parts.

A. Provide a literal interpretation for the following regression coefficients (i.e., explain exactly what b0 and b1 represent—and indicate how many units of change is expected for each dependent variable in the literal interpretation). Note that for each dependent variable explained below, higher scores on that variable represent more of that variable. (2.) Provide predicted values for each dependent variable as directed.

(a) The independent variable is years of work experience and the dependent variable is number of job promotions experienced. The estimate is: b0 = 0 and b1 = .20.

(b) Someone with 10 years of experience is predicted to have how many promotions? Someone with 5 years of experience is predicted to have how many promotions?

(c) The independent variable is test anxiety (higher scores indicate more test anxiety and the range is 0 to 10) and the dependent variable is achievement test scores. The estimate is: b0 = 93.5 and b1 = -3.5.

(d) Someone with an anxiety level of 10 (which is very high) is likely to score what on the achievement test? Someone with anxiety of 0 is likely to score what on the achievement test?
