The wing lengths of houseflies was examined in the paper: Sokal, R.R. and P.E. Hunter. 1955 morphometric analysis of DDT-resistant and non-resistant housefly strains Ann. Entomol. So Amer. 48: 499-507. For the housefly data, the mean wing length was found to be normally distributed with mear 45.5mm and the standard deviation is s = 3.92mm. Answer the following probability question about housefly wing lengths. a) What is the probability that a randomly selected housefly has a wing length of over 50mm b) What is the probability that a randomly selected housefly has a wing length between 30mn and 50mm? c) What is the probability that a randomly selected group of 9 houseflies will have a mean wing length of over 50mm?
