Food: Calories Let x 5 the amount of calories per meal of a healthy adult. Studies show that the population variance of x was approximately s 2 5 5776.

Suppose a recent study on the diets of adult athletes from a random sample of 41 participants gave a sample variance of s2 5 3025. Use a 5% level to test the claim that the variance of an athlete’s calories per meal are less than 5776. Find a 90% confidence interval for the population variance.
