After reviewing his annual costs, a scientist notes that the feed bill always spikes over the summer months. he wonders if his research mice eat more when the air conditioner is operating. luckily his lab has two separate rooms. the scientist divides his mice into two groups of 50, group a and group b, and places them in the separate rooms. both groups are kept in enclosures where they have free access to food at all times. to establish a base line, he tests the hunger level of the two groups by monitoring their food intake for 7 days. the mice in group a ate an average of 31.2 grams of food per day. the mice in group b ate an average of 32.6 grams of food per day. then, the scientist turns on the air conditioner in room a and leaves room b as is. after 7 additional days, the scientist again averages the amount of food eaten by each group. the mice in group a ate an average of 30.7 grams of food per day. the mice in group b ate an average of 31.2 grams of food per day. because the difference between the two groups was so small, and so close to the amount they ate before the experiment, the scientist concludes that the air conditioning did not impact their appetites. read the mice scenario in order to answer the following question. write a valid hypothesis for this experiment.
