Question

(20.60 S-AQ) To study the metabolism of insects,researchers fed cockroaches measured amounts of a sugar solution. After measured the amount of sugar in various tissues. Five roaches fed the sugar D-glucose and dissected after 10 hours had the following Amounts of D-glucose 55.95 68.24 52.73 21.5 23.78 2, 5, and 10 hours, they dissected some of the cockroaches and he researchers gave 9s% confidence interval for the mean amount of D-glucose in cockroach hindguts population grown in the laboratory. We therefore expect responses to be Normal in their The mean (40.01) and the standard deviation (±0.0001) of the SRS are: under these conditions. The insects are a random sample from a uniform

Explanation / Answer

xbar = 44.44
s = 18.5511

critical value, t* = 2.7764

SE = s/sqrt(n) = 18.5511/sqrt(5) = 8.2963
ME = t*SE = 2.7764*8.2963 = 23.0338

CI = (xbar - ME, xbar + ME)
CI = (44.44 - 23.0338, 44.44 + 23.0338)
CI = (21.41, 67.47)
