During the 1996 University of Memphis "Tiger" football season, T. Lane compiled some significant field goal stats. He attempted field goals of the following yardages: 19, 43, 46, 29, 30, 26, 25, 19, 30, 45, 36, 38, 39, 21, 38, 46, 55 and 31. He made field goals of these yardages: 19, 30, 26, 25, 19, 30, 45, 38, 39, 21, 38 and 31.

1. Using the above information, make a back to back frequency table using the following intervals: 10-19 yards, 20-29, 30-39, 40-49, 50-59.

2. Calculate the percentages of field goals made for the five intervals.

3. When should the coach have Lane attempt most field goals?

4. Calculate T. Lane's overall percentage for field goals made.

5. What percentage of field goals did he not make?

6. If Lane continues to do as well this season, how many field goals could he be expected to make if he attempts 21 in all?
