Assume that the weight of cereal in a "12.6- ounce box" is n(μ,0.2 2 ). the food and drug association (fda) allows only a small percentage of boxes to contain less than 12.6 ounces. we shall test the null hypothesis h 0 : μ = 13 against the alternative hypothesis h 1 : μ < 13. (a) use a random sample of n = 25 to define the test statistic and the critical region that has a significance level of α = 0.025. (b) if x = 12.9, what is your conclusion? (c) what is the p-value of this test?
