To find the mean, we need to calculate the sum of the products of each age and its corresponding frequency, and then divide by the total frequency.
Sum of products = (12*4) + (13*9) + (14*16) + (15*14) + (16*7) + (17*7) + (18*4)
Sum of products = 48 + 117 + 224 + 210 + 112 + 119 + 72
Sum of products = 902
Total frequency = 4 + 9 + 16 + 14 + 7 + 7 + 4
Total frequency = 61
Mean = Sum of products / Total frequency
Mean = 902 / 61
Mean ≈ 14.78 years
Therefore, the mean age is approximately 14.78 years.
Sum of products = (12*4) + (13*9) + (14*16) + (15*14) + (16*7) + (17*7) + (18*4)
Sum of products = 48 + 117 + 224 + 210 + 112 + 119 + 72
Sum of products = 902
Total frequency = 4 + 9 + 16 + 14 + 7 + 7 + 4
Total frequency = 61
Mean = Sum of products / Total frequency
Mean = 902 / 61
Mean ≈ 14.78 years
Therefore, the mean age is approximately 14.78 years.
