Question 1 (This problem covers material from Chapters 8-10) The 5 summary statistics for the midterm and final scores of 64 randomly selected students from a large Chemistry class of 2000 students are given in the table below. Avg SD Midterm 76 15 Final 54 20 r= 0.15 a. Find the slope and y-intercept of the regression equation for predicting Finals from Midterms. Final = 0.2 x Midterm + 48.8 (Round answer to 2 decimal place.) Computer's answer now shown above. You are correct. Your receipt no. is 150-1172 (?) Previous Tries b. The SE for the slope is (round to 2 decimal places) 0.16 Computer's answer now shown above. You are correct. Your receipt no. Is 150-3991 (?) Previous Tries c. Find a 95% confidence interval for the slope of the regression line for all 2000 students. Round to 2 decimal places. A 95% Confidence Interval for the slope = ( -0.12 to 0.52 ) Computer's answer now shown above. You are correct. Your receipt no. is 150-598 (?) Previous Tries d. The usual null hypothesis Ho: slopepop = 0 is the same as saying the best prediction for Y = no matter what X is. Fill in the blank with a number using the info given in the summary statistics. Submit Answer ) Tries 0/2 o. Compute the Z statistic to test the null hypothesis, Ho: slopepop - 0 against the alternative HA: slopep > 0 Z - Submit Answer ) Tries 0/2 What is the p-value? (Use this calculator) Reject null? O yes no Submit Answer ) Tries 0/3e. Compute the Z statistic to test the null hypothesis, Ho: slopepop = 0 against the alternative HA: slopepop > 0 Z = Submit Answer ) Tries 0/2 What is the p-value? (Use this calculator) Reject null? O yes O no Submit Answer Tries 0/3 f.Compute the t statistic to test the null hypothesis, Ho: slopepop = 0 against the alternative HA: slopepop > 0 t = Submit Answer Tries 0/3 How many degrees of freedom? t has df Submit Answer Tries 0/2 What is the p-value? Use this online calculator. Reject null? O yes O no Submit Answer Tries 0/3 g. You could have computed the t-statistic in part (f) by multiplying the Z-stat you got in part (e) by O V64/62 O 64/62 O V64/63 0 62/64 O V63/64 O V62/64
