I need help with everything stated in the image and (c) Find the sample correlation coefficient r and the coefficient of determination. (Round your answers to three decimal places.)r = ___r2 = ___What percentage of variation in y is explained by the least-squares model? (Round your answer to one decimal place.)___%(d) Test the claim that the population correlation coefficient ? is positive at the 5% level of significance. (Round your test statistic to three decimal places.t = ____Find or estimate the P-value of the tests statistic -P-value > 0.250-0.125 0. -Reject the null hypothesis. There is insufficient evidence that P>0-Fail to reject the null hypothesis. There is sufficient evidence that P>0-Fail to reject the null hypothesis. There is insufficient evidence that P>0(e) If someone had x = 10 job changes, what does the least-squares line predict for y, the annual salary? (Round your answer to two decimal places.)____ thousand dollars(f) Find Se.
