rison Sentences The average length of prison term in the United States for white collar crime is 34.9 months. A random sample of 40 prison terms indicated a mean stay of 28.8 months with a standard deviation of 8.9 months. At α=0.01, is there sufficient evidence to conclude that the average stay differs from 34.9 months? Use the   P-value method. Use a graphing calculator.  Find the P-value. Round the answer to at least four decimal places.  P-value=
