Answer:
Probability=0.8413
So option A is correct.
Step-by-step explanation:
In order to find the probability that the criminologist will classify all of them as delinquents, we will proceed as following:
We are required to find:
P(m>=75|m-N(80,5))
it can be written as:
1-P(m<75|m-N(80,5))
P(m<75|m-N(80,5)) can be solved as
Z=(75-80)/5
Z=-1
Probability = 1-Z(-1)
Fromm distribution table:
Probability=1-0.15866
Probability=0.8413
So option A is correct.
