Problem 8CQQ

In general, what does “degrees of freedom” refer to? For the sample data described in Exercise, find the number of degrees of freedom, assuming that you want to construct a confidence interval estimate of ?. Exercise Six human skulls from around 4000 B.C. were measured, and the lengths have a mean of 94.2 mm and a standard deviation of 4.9 mm. If you want to construct a 93% confidence interval estimate of the mean length of all such skulls, what requirements must be satisfied?
