You can calculate the Pvalue for a chi-square test using technology. After calculating the standardized test statistic, use the cumulative distribution function (CDF) to calculate the area under the curve, Use the P-value method to test the claim, A school administrator claims that the standard deviation for eighth-grade students on a test is greater than 37 points. A random sample of 25 eighthgrade students has a standard deviation of 37.5 points' At a = 0.05, is there enough evidence to support the administrators claim?
