= 1500 SD = 200 The scatter diagram is football shaped and r = 0.55 (a) ( 7 points) What is the equation of the regression line for predicting the yearly harvest from the number of sunny days? (b) ( 4 points) If this year the number of sunny days before August was 127, what would your estimate of the size of this years wheat crop be? (c) (c) ( 8 points) The Ukraine needs a minimum of 1400 tons of wheat to prevent a famine. Of the years with 127 sunny days before August, what percentage are famine years? (d) (d) ( 6 points) If a particular year had a final harvest of 1530 tons of wheat, what would you use for your estimate of the number of sunny days before August that year?
