Fоr а study оf the develоpment of the thymus glаnd, reseаrchers weighed the glands of six chick embryos after 14 days of incubation. The thymus weights (mg) were as follows: 33.8 27.3 30.8 32.6 43.5 47.6 a. Find a 98% confidence interval estimate for the population mean weight of the thymus glands of chick embryos. Show your work for full credit (6 points) b. Interpret the confidence interval in context of the problem. (2 points) c. If we kept the same level of confidence (98%) but take 4 times as large of a sample size, in general what would happen to the width of the confidence interval? You do NOT need to find the new interval (1 point). d. Find a 95% confidence interval estimate for the population variance of the thymus glands of chick embryos.
