An article in the Journal of Engineering Tribology discusses several experiments involving various lubricants. In one experiment, 45 steel balls lubricated with purified paraffin were subjected to a 40 kg load at 600 rpm for 60 minutes. The average wear, measured by the reduction in diameter, was 673.2 , and the standard deviation was 14.9. Assume that the specification for the lubricant is that the mean wear must be less than 675.
Required:
Find the P-value.
