Blue Bird Consolidated Theaters has more than 600 theaters located across the

country.

Each theater has four separate screens, and the customer can choose

from one of four different movies.

The president of Blue Bird Consolidated

wants to know if a variety of shows (spy, comedy, horror, children's) or a

coordinated bill (all spy, all comedy, etc.) has any effect on the total ticket sales

at a theater.

The president randomly assigned 47 theaters to use a variety of

shows and 53 other theaters to use a coordinated bill of shows.

For all theaters,

total tickets sales for one week were recorded.

Using the following data and a
