A random sample of 25 women resulted in systolic blood pressure levels with a mean of 109 and a standard deviation of 5.6. A random sample of 61 men resulted in systolic blood pressure levels with a mean of 144 and a standard deviation of 2.4. Use a 0.025 significance level and the critical value method to test the claim that blood pressure levels for women vary more than blood pressure levels for men. Enter the smallest critical value. (Round your answer to nearest ten-thousandth.)
