Suppose a company makes skateboard wheels with a diameter of 62 mm. When the machine that manufactures the wheels is functioning properly, it produces wheels whose diameters are normally distributed with a mean of 62 mm and a standard deviation of 3.2 mm. The machine gets out of tolerance over time, and can produce wheels that have either a larger or smaller mean diameter. Therefore, quality control inspectors randomly select wheels and measure their diameters. A recent random sample of 64 wheels had a mean of 62.4 mm. Required:
Draw the shaded areas that correctly represents the p-value of the sample results.
