Assignment 4.1
Suppose you are trying to estimate the average miles per gallon for a new brand of car.
You take a random sample of 40 cars, and, for this sample, the average miles per gallon
is 32 and the standard deviation is 2.2. Answer the following qu
Assignment 4.2
Suppose a car dealer tells you that specific cars get 35 miles per gallon on
average. You would be able to use hypothesis tests to test whether or not
this value might be correct.
Why would you use a hypothesis test instead of a confidence

Without the correct type of data, any analysis you do will be meaningless. Because of this,
one of the most important steps in gathering data is to know what type of data to collect.
For this assignment, you will extract data from actual people and analyz
