Bone mineral density (BMD) was measured for seven postmenopausal women: 1.7, 1.6, 1.4,1.3, 2.1, 2.3, 1.5 g/cm2. Find a 99% confidence intervar for the mean
CI99 = mean ± 2.58(sd/√n)
You will need to calculate the mean and standard deviation of the data given.
Sample size = 7
Substitute values into the formula and calculate the confidence interval.
I'll let you take it from here.
