I will be comparing Altimeter brand A and Altimeter brand B to determine if there are significant difference between them.

The average of Altimeter Brand A's population is equal to the average of the Altimeter Brand B population.

I will be using a two-sample t-test.

The alpha (a) level that I will be using is .05
