2/3 years = 2/3 * 12 = 8 months
1/3 years = 1/3 * 12 = 4 months
Convert all into months ; 135 months, 125 months, 128 months, 160 months
Hence,
Mean = Sum of observations / No. of observations
⇒ 135 + 125 + 128 + 160 / 4 = 548/4 = 137 months = 11 years and 5 months.
Mean of ages of children = 11 years and 5 months
1/3 years = 1/3 * 12 = 4 months
Convert all into months ; 135 months, 125 months, 128 months, 160 months
Hence,
Mean = Sum of observations / No. of observations
⇒ 135 + 125 + 128 + 160 / 4 = 548/4 = 137 months = 11 years and 5 months.
Mean of ages of children = 11 years and 5 months
