To study the metabolism of insects, researchers fed cockroaches measured amounts of a sugar solution. after 2, 5 and 10 hours, they dissected some of the cockroaches and measured the amount of sugar in various tissues. five roaches fed the sugar d-glucose and dissected after 10 hours had the following amounts, in micrograms, of d-glucose in their hindguts: 55.95, 68.24, 52.73, 21.50 and 23.78.assume the d-glucose content follows a normal distribution, construct a 95% confidence interval for the mean amount d-glucose in cockroach hindguts under these conditions.
