The cholesterol levels of adult males are approximately normally distributed with a mean of 224 mg/dL and a variance, oʻ, of 514. Some researchers claim that the variance of cholesterol levels of adult males is greater than 514. A sample of 19 adult males' blood tests had a mean of 222.5 mg/dL and a variance of 1094. Is there enough evidence to conclude, at the 0.01 level of significance, that the variance of cholesterol levels of adult males is greater than 514? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified below. (If necessary, consult a list of formulas.)
