Step A: To find the mean of the scores 14,15,15,16,17,18,19,20,22,2414, 15, 15, 16, 17, 18, 19, 20, 22, 24.

Step 1: Calculate the sum of the scores.

Sum=14+15+15+16+17+18+19+20+22+24=180\text{Sum} = 14 + 15 + 15 + 16 + 17 + 18 + 19 + 20 + 22 + 24 = 180

Step 2: Count the number of scores.

There are 10 scores.

Step 3: Calculate the mean.

Mean=SumNumber of scores=18010=18\text{Mean} = \frac{\text{Sum}}{\text{Number of scores}} = \frac{180}{10} = 18

Final answer for part A: 18\boxed{18}


Step B: To calculate the frequency distribution table.

Step C: Draft of the frequency distribution table.

Frequency: 1   2   1   1   1   1   1   1   1
