In a particular company, 10 employees are selected at random and their salary and years of experience are recorded. The results are given in the table below: 1. Years Experience and Starting Salary Years Salary 82 2 56 4 64 77 7 92 23 1 41 8 80 59 3 47 We would like to estimate a regression that investigates how salary is determined by years of experience, i.e., Salary = bo + b, Years For the above data find: а. The regression slope b: (use the equations found in the lecture notes) b. The regression intercept bo: (use the equations found in the lecture notes) C. If SSR = 3544.576 and SST = 4084.9, what is SSE? d. What is R2 for this model? If the standard error for b, is 1.031 what is the t-score and p-value for testing Ho:B1 = 0. е. f. Using the p-value for the test in (e.) at what value of alpha would you reject null hypothesis? g. What is the correlation between y and ŷ?
