Proportions
According to a study conducted by
Ace Computers, 59% of men and 70% of women say that weight is an extremely/very
important factor in purchasing a laptop computer. Suppose this survey was
conducted using 374 men and 481 women. Do these data show enough evidence to
support the conclusion that there is no difference in the proportion of men and
women who think weight is a factor in purchasing a laptop? Use a 5% level of
significance.
