You can calculate the P-value 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 hospital spokesperson claims that the standard deviation of the waiting times experienced by patients in its minor emergency department is no more than 0.5 minutes. A random sample of 24 waiting times has a standard deviation of 0.7 minutes. At a = 0.01, is there enough evidence to reject the spokesperson's claim? Identify the null and alternative hypotheses.
