Answer:
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
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
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
