Question

Question;Question 4-13: Students in a management science class have just;received their grades on the first test. The instructor has provided;information about the first test grades in some previous classes as well as the;final average for the same students. Some of these grades have been sampled and;are as follows;STUDENT 1;2 3 4 5 6 7 8 9;1st test;grade 98 77 88 80 96 61 66 95 69;Final;average 93 78 84 73 84 64 64 95 76;(a);Develop a regression model that could be used to predict the final average in;the course based on the first test grade.;(b);Predict the final average of a student who made an 83 on the first test.;(c) Give;the values of r and for this model. Interpret the value of in the context of;this problem.;Question;4-14: Using the data in Problem 4-13, test to see if there is a statistically;significant relationship between the grade on the first test and the final;average at the 0.05 level of significance. Use the formulas in this chapter and;Appendix D.;Question 4-15;Using computer software, find the least squares regression line;for the data in Problem 4-13. Based on the F test, is there a statistically;significant relationship between the first test grade and the final average in;the course?;Question;4-19: Bus and subway ridership in Washington, D.C., during the summer months is;believed to be heavily tied to the number of tourists visiting the city.
