only final ans no need for steps/explaination (fast please) A mixture of pulverized fuel ash and Portland cement to be used for grouting should have a compressive strength of more than 1,300kN/m2, The minture wit not be used unless experimental evidence indicates conclusively that the strength specification has been met Suppose compressive strength for speclmens of this minture is riarmally distributed with =65. Let denote the true average compressive strength If X=1,340, find the P-value. (Round your answer to four decimal places.) P-value = State the mean and standard deviation (in KN/m2 ) of the test statistic. (Round your standard deviation to three decimal places.) mean - kN/m2 standard deviation x kN/m2 For a test with a =0.01, what is the probabily that the mixture will be judged unsatisfactory when in fact is =1.350 (a type II error)? (Raund your anner to four decimal places.)
