Answer:
Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.
Step-by-step explanation:
From. The plot given :
We could approximate the proportion of females older than 60 as follows _
COUNTRY A :
60 - 69 = 0.105
70 - 79 = 0.065
80 - 89 = 0.038
90+ = 0.01
Total = About 0.218
COUNTRY B :
60 - 69 = 0.14
70 - 79 = 0.11
80 - 89 = 0.07
90+ = 0.02
Total = About 0.34
From the estimated proportion, the proportion of females on country B is more than the proportion in country A.
