1. Over a sample of 47 voyages. Mr. Sulu found theStarship Enterprise traveled a mean of 658light-years-per-dilithium-crystal (lypdc) with a standard deviationof 76 lypdc.
(a) Find a point estimate for the mean lypdc on all starshipvoyages.
(b) Find the 95% margin of error for the estimate in (a).
(c) Make a 95% confidence interval for the mean lypdc on allstarship voyages. Interpret the interval.
