Hi! I pretty much don't understand these problems that were presented on my Statistics class An engineer wants to determine how the weight of a car, x, affects gas mileage, y (MPG). The followingdata represent the weights of various cars and their miles per gallon.Make a scatter plot. (Carefullychoose units on both axes; no need tostart at 0, but make them not too small!Do not omit axis labels and the title.)Describe the relationshipbetween Car Weight and MPG.Justify. Give the correlationcoefficient to three decimalplaces.

(Round to one decimal place if needed.)

Since you have asked multiple question, according to our guidelines we will solve the first question…
