A researcher would like to determine whether humidity can have an effect on eating behavior. It is known that under regular circumstances, laboratory rats eat an average of µ = 10 grams of food each day. The researcher selects a random sample of n=15 rats and places them in a controlled atmosphere room where the relative humidity is maintained at 90%. The daily food consumption for each of these rats is as follows:
Food Consumption
__________________________________
9.1 8.3 7.6 10.2 8.4
6.9 9.3 10.7 11.2 9.8
8.5 12.1 8.4 7.7 9.2
