According to industry specifications, the standard deviation of gasket thicknesses for a given application must be no more than 3 thousandths of an inch. In a random sample of 25 gaskets produced by one of the firms, the sample standard deviation is found to be 3.7 thousandths of an inch. Assuming the population of thicknesses is normally distributed, and using 5 0.025, examine whether the firm could be in violation of the industry specification. Based on the chi-square table, what is the most accurate statement that can be made about the p-value for the test?
