Comparing Populations Based on Random Samples

T.i.P.S.

Students should be able to compare data from random samples and interpret their implications about the differences of the whole population. This could include, but is not limited to, comparing their shapes, centers, spreads, or percentages based on the total population.

Example

The data from two random samples of 100 students from two different schools regarding their favorite candy preferences are given below.

Using the data from the random samples, predict and compare the types of candy that should be sold in the school store. Justify your thinking.
