1) A sample of 12 recent births at a local hospital in a small
town has the following birth weights (in ounces): 89, 122, 137,
144, 98, 113, 124, 138, 108, 117, 105, 99
a) Compute the sample mean and standard deviation of the birth
weights. (You can use technology to find this.)
b) Assume the population distribution of birth weight is
approximately normal. Construct the 95% confidence interval to
estimate the mean birth weight of all babies born in...
