Explanation / Answer

Select the null and the alternative hypotheses for the following tests: A.Test if the mean weight of cereal in a cereal box differs from 18 ounces

Ho : miu = 18

H1 : miu is not equal to 18

B.Test if the stock price increases on more than 60% of the trading days.

Ho : p = 0.60

H1 : p > 0.60

Americans get an average of less than seven hours of sleep

Ho : miu = 7

H1 : miu < 7
