Acertain type of stainless steel powder is supposed to have a mean particle diameter of µ = 15µm. a random sample of 87 particles had a mean diameter of 15.2 µm, with a standard deviation of 1.8 µm. a test is made of h0 : µ = 15 versus h1 : µ =! 15. a. find the p-value. b. do you believe it is plausible that the mean diameter is 15 µm, or are you convinced that it differs from 15 µm? explain your reasoning.
