Among other food items produced by the FLDSMDFR are spaghetti with meatballs, and roasted chicken. It is assumed that the production time of a randomly selected plate of spaghetti with meat- balls is normally distributed with u = 5 and o = 0.5 (both in minutes). (A) [4 marks] Among plates of spaghetti with meatballs prepared in more that 4 minutes, what pro- portion actually require a preparation time between 5 and 6 minutes? Use the fact that @(2) ~ 0.977 to get a numerical answer to the above. (B) [4 marks] You are told that the FLDSMDFR generally takes twice as much time to produce roasted chickens, compared to plates of spaghetti with meatballs. Based on this, what proportion of roasted chickens require more than 12 minutes of preparation time
