In testing a proportion, which of the following statements is incorrect? multiple choice when the sample proportion is p = .02 and n = 150, it is safe to assume normality. an 80 percent confidence interval is narrower than the 90 percent confidence interval, ceteris paribus. the sample proportion may be assumed approximately normal if the sample is large enough. using α = .05 rather than α = .01 would make it more likely that h0 will be rejected.

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?
