Your company is developing a better means to eliminate cockroaches from buildings. in the process, your r& d team studies the absorption of sugar by these insects. they feed cockroaches a diet containing measured amounts of d-glucose. the cockroaches are killed at different times after eating, and the concentration of this sugar in various body parts is determined by a chemical analysis. five cockroaches dissected after 10 hours had the following amounts (in micrograms) of d-glucose in their hindguts. assume these amounts are normally distributed. 54.2, 68.3, 49.8, 21.7, 37.8 find a 95% confidence interval for the mean amount of d-glucose in cockroach hindguts under these conditions.
