Answer to Problem 2E
The truth about
Explanation of Solution
Given:
The probability of a false positive is
Concept used:
Definition of relative frequency :-A relative frequency is the fraction of times an answer occurs that is the relative frequencies divide each frequency by the total number of student in the sample
Calculation:
A relative frequency is the fraction of times an answer occurs that is the relative frequencies divide each frequency by the total number of student in the sample
That is
This probability as a long run relative frequency use a polygraph machine on many people who are all telling the truth about
(b)
To find:
The probability of false positive or a false negative
(b)
Explanation of Solution
Given:
The probability of a false positive is
Concept used:
Definition of relative frequency :-A relative frequency is the fraction of times an answer occurs that is the relative frequencies divide each frequency by the total number of student in the sample
Calculation:
A relative frequency is the fraction of times an answer occurs that is the relative frequencies divide each frequency by the total number of student in the sample
It seems that claiming someone is lying when telling the truth is a more serious error in this case a false positive or a false negative
