The mean is approximately
enter your response here years. (Round to two decimal places as needed.)
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.
