To find the mean, we first need to calculate the sum of all the values multiplied by their respective frequencies:
(14*6) + (15*9) + (16*11) + (17*17) + (18*7) + (19*7) + (20*4) = 276
Next, we need to find the total frequency:
6 + 9 + 11 + 17 + 7 + 7 + 4 = 61
Finally, we can calculate the mean by dividing the sum by the total frequency:
276 / 61 ≈ 4.52
Therefore, the mean age is approximately 4.52 years (rounded to two decimal places).
