The break-even hay yield for your farm is 2200 kg/ha. A lower yield leads to economic losses. The yield in your area is known to be normally distributed with µ= 2500 kg/ha, ? = 300 kg/ha.
- Draw the relative frequency distribution and cumulative distribution of yield and show the location of the break-even yield.
- Calculate the probability of having economic losses and shade the corresponding area under the curve.
- Calculate the probability of NOT having losses.
- Estimate the probability that your yield will be between 1900 and 3100 kg/ha.
