Answer:

conclusion : Life expectancy of women > Life expectancy of men

Step-by-step explanation:

A) Mean life expectancy of women

from the attached table

mean life expectancy of women = ∑fx / ∑f

∑fx = 1523

∑f = 20

mean = 1523 / 20 = 76.15

The line graph shows a negatively skewed distribution

B) Mean life expectancy of Men

from the attached table

mean life expectancy of Men = ∑fx / ∑f

∑fx = 1432

∑f = 20

mean = 1432 / 20 = 71.6
