Part F What is the probability that Dora, the 53-year-old you're considering for a 20-year policy, lives to be 73 years old? Remember that Dora is a

Hispanic female.

The probability that she lives 73 years is 0.1897

Step-by-step explanation:

Here the random variable x= 83  years where x is the average life span of a Hispanic female. the mean would be 41.5 years

We have to find the probability that Dora lives  73 years. Her present age is 53 years.

In mathematics this can be re written as  P(x=73)

Variance= ∑ ( x-x`)/1= 83-41.5/1= 41.5

Standard deviation = √var= √41.5= 6.4 years

At x= 73 we have z= 73-41.5/6.4= 4.92

Using the z tables the value under the area 4.92 = 0.1897

So the Probability that she lives 73 years is 0.1897

86.05%

Step-by-step explanation:

Hi friends! I am using Edmentum and was asked this question and used the graphs they gave us the link to. If you are not using Edmentum or do not have the graph you should go off the other answer post! As for my Edmentum friends here is what I did...

82625 / 96022 = 0.8604

0.8604 x 100 = 86.05

hope this helps!
