In addition to the blood types A, B, AB , and O, a person’s blood may be classified as Rh positive or Rh negative. In the United States, about 15% of the white population is Rh negative, while the percent is much lower in other racial groups. The director of a blood bank wants to estimate the probability that in a random group of 50 unrelated white donors, at least 8 will have Rh negative blood. If she generates random numbers to simulate this problem, how could she assign the numbers to the two blood types?

Question

In addition to the blood types A, B, AB , and O, a person’s blood may be classified as Rh positive or Rh negative. In the United States, about 15% of the white population is Rh negative, while the percent is much lower in other racial groups. The director of a blood bank wants to estimate the probability that in a random group of 50 unrelated white donors, at least 8 will have Rh negative blood. If she generates random numbers to simulate this problem, how could she assign the numbers to the two blood types?

A.Assign the numbers 0 through 8.5 to people with Rh positive blood and the numbers 8.6 through 9.9 to people with Rh negative blood.

B.Assign the integers 00 through 84 to people with Rh negative blood and the integers 85 through 99 to people with Rh positive blood.

***C.Assign the integers 00 through 85 to people with Rh positive blood and integers 86 through 99 to people with Rh negative blood.

D.Assign the integers 00 through 84 to people with Rh positive blood and the integers 85 through 99 to people with Rh negative blood.

I'm sorry, I don't understand what you're referring to with "-180". Could you provide more context or information so I can better assist you?

Answer 2

To assign the numbers to the two blood types in order to simulate the problem, the director of the blood bank should choose option C. Assign the integers 00 through 85 to people with Rh positive blood and integers 86 through 99 to people with Rh negative blood.

This means that the numbers 00 to 85 will represent individuals with Rh positive blood, and the numbers 86 to 99 will represent individuals with Rh negative blood.

By using this assignment, the director can generate random numbers between 00 and 99 to represent the blood types of the randomly selected donors. Each time a number falls between 00 and 85, it will be considered Rh positive blood, and each time a number falls between 86 and 99, it will be considered Rh negative blood.

By generating and analyzing the results of these random numbers, the director can estimate the probability of at least 8 out of 50 unrelated white donors having Rh negative blood.
