An agricultural scientist is interested in the relationship between the amount of fertilizer used, measured in bags per acre, and the yield of wheat, measured in bushels per acre:
a. Draw a scatter diagram.
b. Calculate the set of elementary estimates of (3. Find the median slope estimate.
c. Calculate the set of elementary estimates of Q. Find the median intercept estimate. Write the equation of the regression line.
d. Calculate the estimated yield of wheat if 2 bags of this fertilizer are to be used.
e. Do the data support the claim that an increase in fertilizer results in an increased yield of wheat? State Ho and Ha and test. Find the P-value.
