Calculation: We have to test Null Hypothesis based on given information. Type I error will result in the rejection of a large number of good tires. Type II error of passing a faulty batch of tires can result in fatal accidents on the roads. Alpha = 5%‚ Sample Size = 40‚ for calculating Beta u = 2790 psi. H0 : u> 2‚800
