Suppose that a customer is purchasing a car. He conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. He conducts this experiment 15 times on each car and records the number of miles driven.

There are some details missing which i have added when solving the question. it says calculate the mean of Car 1 and car 2

Step-by-step explanation:

The detailed steps and appropriate calculation to determine the mean of car 1 and car 2 is as shown in the attachment.

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

find the magnitude of the trig term
