Question

You wrote a program to compare the portion of drivers who were on the phone.

Which statements are true? Select 4 options.


Responses

It is important to test your program with a small enough set of data that you can know what the result should be.


You could modify the program to allow the user to enter the data.

Your program compared an equal number of male and female drivers.


A different set of observations might result in a larger portion of male drivers being on the phone.

Even when confident that the mathematical calculations are correct, you still need to be careful about how you interpret the results.
