(c) Find Beta, the standardized regression coefficient, for theregression of Zy on Zx. Show all yourcalculations and interpret the result.
(e) what is the squared R (R2)? Interpret thestatistics.
(f) Calculate the standard error of b, the unstandardizedregression of coefficient. Show all your calculations. In words,explain the meaning of this statistic and how it can be used ininferential statistics.
g) These six occupational titles listed above wererandomly chosen from a long list of occupational tittles. Using alevel of significance = .05, test the null hypothesis (that theregression coefficient = 0 for the population). Show all yourcalculations.
(h) What is the 90% confidence interval for the populationunstandardized regression coefficient? Provide a verbalinterpretation for this confidence interval which goes beyond thestatement: “the probability that the calculated intervalcontains the population parameter is . 90”.
