The mean age of 9 women in an office is 27 years old.
2 answers:
26 to nearest year
We require the total of the sums of ages for both groups before calculating the mean for all 16
using mean =
Women
27 = ( cross- multiply )
sum = 9 × 27 = 243
Men
25 = ( cross- multiply )
sum = 7 × 25 = 175
Total sum of all 16 = 243 + 175 = 418
mean = = 26 ( to nearest year )
That would have to be that age of
26
