Answer:
0.945200708
Step-by-step explanation:
In this question, we are asked to calculate the probability that a person selected at random would live less than 65.
To solve this problem, what we need to do is to first calculate the z-score.
Mathematically, z = (x-mean)/standard deviation
According to the question, the mean is 53 years and the standard deviation is 7.5
Substituting these values in the z-score equation:
Z-score = (65-53)/7.5 = 12/7.5 = 1.6
We proceed to use the z-score table to obtain the probability. Using the table, z score of 1.6 corresponds to a probability of
0.945200708
