A market research firm conducted a survey to determine the average amount of money consumers spend on chewing gums each week. A sample of 100 such consumers revealed that the sample mean is $20 and the sample standard deviation is $5. What is the probability that a sample of 100 consumers spend between $19 and $21 on chewing gums

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
