Abolt manufacturer is very concerned about the consistency with which his machines produce bolts. the bolts should be 0.26 centimeters in diameter. the variance of the bolts should be 0.025. a random sample of 11 bolts has an average diameter of 0.25cm with a standard deviation of 0.0661. can the manufacturer conclude that the bolts vary from the required variance at α=0.05 level?
