Of 1936 people who came into a blood bank to give blood, 200 people had high blood pressure. Estimate the probability that the next person who comes in to give blood will have high blood pressure.

Question

Of 1936 people who came into a blood bank to give blood, 200 people had high blood pressure. Estimate the probability that the next person who comes in to give blood will have high blood pressure.

Answer 1

To estimate the probability that the next person who comes into the blood bank will have high blood pressure, we can use the concept of relative frequency.

To do this, we need to calculate the proportion of people with high blood pressure among those who came into the blood bank.

Given that out of 1936 people who came to give blood, 200 had high blood pressure, we can set up the ratio:

Proportion of people with high blood pressure = Number of people with high blood pressure / Total number of people

Proportion of people with high blood pressure = 200 / 1936

Calculating this fraction, we find:

Proportion of people with high blood pressure ≈ 0.1034

Therefore, we estimate that the probability that the next person who comes into the blood bank will have high blood pressure is approximately 0.1034 or 10.34%.
