I Need 2 Pleas

Students in 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 follow: 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 students who made an 83 on the first test. c) Give the value of r and for this model. Interpret the value of in the context of this problem. 2.From historical data, Harry's Car Wash estimates that dirty cars arrive at the rate of 8 cars per hour all day Saturday. With a crew working the wash line, harry figures that car can be cleaned at the rate of one every 6 minutes. One car at a time cleaned in this example of a single-channel waiting line. Assuming poison arrival and exponential service times, find that Average number of cars in line. b) Average time a car waits b Students in 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.
