(CO 3) Consider the table below.

What is P(over 60’)?

64.6%

25.7%

74.3%

71.8%

Answer 1

Answer #1

Age Group	Frequency	Relative frequency=Class frequency/Total frequency
18-29	9831	0.236566643
30-39	7845	0.188776861
40-49	6869	0.165291046
50-59	6323	0.152152465
60-69	5410	0.130182641
70 and over	5279	0.127030344
Total	41557	1

P(Over 60) =0.1302+0.1270

=0.2572

i.e. 25.7%
