Question

The following table shows the number of males in a country in 2000, broken down by age. Numbers are in millions. 75 Age 0-18 18-25 25-35 35-45 45-55 55-65 65-75 and over Number 32.3 13.4 21.3 22.1 18.4 11.2 8.7 5.9 rounded to four decimal places). 75 and over Age 0-18 18-25 25-35 35-45 45-55 55-65 65-75 Probability | 0.2423 ?| 0.1005 v10.1598 ?| 0.1658 | 0.1380 / | 0.0840 V | 0.0653 v, | 0.0443 Use the distribution to compute the following. (Round your answers to four decimal places.) (a) P(25 s X s 65) 0.5476 (b) P(XS 18) 0.2423 (c) PX 2 15) 0.7577X

Explanation / Answer

Since both part a and part b answers are correct, im assuming u only need Part c)

c) The value of P(X>=15) is obtained by

P(X>=15)=1-P(X=0-18)+P(X=15-18)

=1-0.2423+[0.2423/19]*3

= 0.7959
