During the fall harvest season in the United States, pumpkins are sold in large quantities at farm stands. Often, instead of weighing the pumpkins prior to sale, the farm stand operator will just place the pumpkin in the appropriate circular cutout on the counter. When asked why this was done, one farmer replied, "I can tell the weight of the pumpkin from its circumference." To determine whether this was really true, a sample of 15 pumpkins were measured for circumference and weighed with the following results.

1. Assuming a linear relationship, use the least squares method to find the regression coefficients b0 and b1.
2. Interpret the meaning of the slope b1 in this problem.
3. Predict the average weight for a pumpkin that is 60 centimeters in circumference.
4. At the 0.05 level of significance, is there evidence of a linear relationship between the circumference and the weight of a pumpkin? Explain.
