Concept explainers
(a)
To state the question of interest using the language of probability.
(a)
Explanation of Solution
By looking at the question, the question of interest made using the language of probability is as follows:
What is the probability of selecting
This is the question stated using the language of probability.
(b)
To explain how would you use random digits to imitate one repetition of the process and find out what variable you would measure.
(b)
Answer to Problem 20E
The variable measured is the number of vowels.
Explanation of Solution
To use random digits to imitate one repetition of the process, we will do as;
Use two digits numbers.
If the number is between
If the number is between
Randomly choose
Then count the number of vowels that you have among the
Thus the variable measured is the number of vowels.
(c)
To use the line of random digits given to perform one repetition and explain the process.
(c)
Explanation of Solution
As in the question given the random digits as-
Select the first two digit number. If the number is between
This is explained as,
Thus the numbers selected as vowels are three as:
(d)
To explain what conclusion would you draw.
(d)
Explanation of Solution
As we know that If the number is between
If the number is between
Thus given two times when all
Since the percentage is below
Hence the conclusion.
