Lesson Worksheet: Prediction Using Probability Mathematics • 7th Grade
In this worksheet, we will practice predicting the actions of a larger group using a sample and finding the expected value.
A factory produces two types of shirts: A and B. The table shows how many shirts of each type were sold in 5 samples of 100 shirts from 5 different shopping malls.
|Sales of Type A||35||66||29||44||53|
|Sales of Type B||65||34||71||56||47|
If the factory sells 3,000 shirts, how many of them do you expect to be of type A?
