the partially filled contingency table gives the relative frequencies of the data on age (in years) and sex from the residents of a retirement home.

what is the probability that a resident is in the age group 60-69?

a.

0.385

c.

0.35

b.

0.37

d.

0.4

Answer with Step-by-step explanation:

                    Male             Female                

60-69            0.17                 0.2

70-79              0.1                  0.2

Over 79          0.13                 0.2

As we can clearly see from the table above that probability that a resident is in age group 60-69 is:

0.17+0.2

= 0.37

Hence, correct option is:

c.  0.37

the answer is actually D

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
