The yearly wheat yield per acre on a farm is normally distributed withμ=35bushels and the standard deviation σ=8 bushels. (a) Draw a normal curve and shade the area under the curve that represents the probability that an acre will yield between 19 and 35 bushels. (b) Is the area the same as the area between μ-2σ and μ? (c) Find the percentage of area over the interval between 19 bushels and 35 bushels. (d) What is the probability that the yield will be between 19 and 35 bushels per bushel?
