Hi there, I am doing my statistics homework and am having trouble with a few problems. I sincerely appreciate any help I receive! :)
According to a local chamber of commerce, in 1993, 5.9% of local area residents owned more than five cars. A local car dealer claims that the percentage has increases. He randomly selects 180 local area residents and finds that 12 of them own more than five cars. Test this car dealer’s claim that the (alpha = .05) level of significance.
Use the binomial theorem.
Show that you can’t use z.
