Amixture of pulverized fuel ash and portland cement to be used for grouting should have a compressive strength of more than 1300 kn/m2. the mixture will not be used unless experimental evidence indicates conclusively that the strength specification has been met. suppose compressive strength for specimens of this mixture is normally distributed with σ = 64. let μ denote the true average compressive strength. let x denote the sample average compressive strength for n = 11 randomly selected specimens. consider the test procedure with test statistic x and rejection region x is 1331.26. what is the probability distribution of the test statistic when h0 is true?
