Question 2 According to an SSA study, around 38% of 65-year old women will live to at least 90. An insurance company has a part of its portfolio made of life insurance policies sold to 65-year old women. Based on the SSA study the insurance company expects that 62% of 65-year old women will pass away before reaching the age of 90. A simple random sample of 250 is taken. Use the normal approximation along with the continuity correction factor to find the probability that at most 159 women in the sample will pass away before reaching the age of 90. • Let X be the number of females out of 250 that pass away before reaching the age of 90.
