A Psychology professor, teaching at a large university, wants to
know whether there is a difference between the IQs of male and
female students in attendance. She randomly and independently
selects 20 female and 20 male students and has them take the IQ
test. The resulting IQ data are as follows:
Female: 130, 117, 124, 120, 125, 109, 100, 118, 127, 130, 126, 118,
131, 104, 130, 116, 122, 115, 129, 117
Male: 106, 114, 134, 120, 107, 131, 133,...
The following data represent the lifetimes (in hours) of a
sample of 40 transistors: 112, 121,...
