4-13 Students in a management science class have just re- ceived 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 Finalaverage 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 r2 for this model. Inter- pret the value of r2 in the context of this problem

Sheila is looking at some information for the obstacle course she is interested in completing. The x-coordinate is the number of the obstacle, while the y-coordinate is the average time to complete the obstacle, measured in minutes. (1, 8.25), (2, 9.075), (3, 9.9825), (4, 10.98075) Help Sheila use an explicit formula to find the average time she will need for the 8th obstacle. A. f(8) = 8.25(1.1)^8; f(8) = 17.685B. f(8) = 8.25(1.1)^7; f(8) = 16.077C. f(8) = 1.1(8.25)^7; f(8) = 2861345D. f(8) = 1.1(8.25)^8; f(8) = 23606102
