Answer 1

To find the mean, we first need to calculate the sum of the products of the values and their frequencies.

(10*7) + (11*9) + (12*17) + (13*16) + (14*8) + (15*4) + (16*2) = 70 + 99 + 204 + 208 + 112 + 60 + 32 = 785

Next, we divide the sum by the total frequency:
785 / 63 = 12.460317

Rounded to two decimal places, the mean age is approximately 12.46 years.
