... A sample of 400 college students was asked a question about cheating. 12% said if they witnessed cheating, they would report it to the professor. Suppose that if we could ask all college students, 12% would answer Yes. The proportion p = 0.12 is a parameter that describes the population of all colle ...

Because the t distributions are symmetric, P (t ≤ −0.94) = P (t ≥ 0.94). Search the df = 14 row of Table B for entries that bracket t = 0.94 (see the excerpt below). ...
