The mass of plants in a botany lab are normally distributed witha mean of 54 grams and a standard deviation of 6.5 grams. Use thisto compute : a. The probability that one randomly chosen plant willhave a mass that less than 49.25 grams b. The probability that onerandomly chosen plant will have a mass that is between 52 grams and62 grams. c. The mass of a plant which weighs less than the top 15%of plants in the lab. d. The probability that 25 randomly chosenplants will have a mean mass of no more than 50 grams
