Question

Penicillin is produced by the Penicillium fungus, which is grown in a broth whose sugar content must be carefully controlled. Several samples of broth were taken on three successive days, and the amount of dissolved sugars, in milligrams per milliliter, was measured on each sample. The results were as follows. Can we conclude that the mean sugar concentration differs among the three days? Use the 05.=αlevel of significance.

Day 1    4.8 5.1 5.1 4.8 5.2 4.9 5.0 4.9 5.0 4.8 4.8 5.1 5.0

Day 2     5.4 5.0 5.0 5.1 5.2 5.1 5.3 5.2 5.2 5.1 5.4 5.2 5.4

Day 3     5.7 5.1 5.3 5.5 5.3 5.5 5.1 5.6 5.3 5.2 5.5 5.3 5.4

I need an example of this problem using a TI84 calculator. Thanks
