Researchers measured the bone mineral density of the spines of 94 women who had taken the drug CEE. (See Example 6.3.4, which dealt with hip bone mineral density.) The mean was 1.016 g/cm2 and the standard deviation was 0.155 g/cm2. A 95% confidence interval for the mean is (0.984,1.048).
(a) True or false (and say why): 95% of the sampled bone mineral density measurements are, between 0.984 and 1.048.
(b) True or false (and say why): 95% of the population bone mineral density measurements are between 0.984 and 1.048.
