Problem 13E

A method of applying zinc plating to steel is supposed to produce a coating whose mean thickness is no greater than 7 microns. A quality inspector measures the thickness of 36 coated specimens and tests H0.:µ ≤ 7 versus H1:µ, >7. She obtains a P-value of 0.40. Since P > 0.05, she concludes that the mean thickness is within the specification. Is this conclusion correct? Explain.
