(a) What is the probability that the person is less than 19
years old?Round your answer to four decimal places.
(b) What is the probability that the person is more than 30 years
old? Round your answer to four decimal places.
Homework Answers
answer)
Probability is given by favorable/total
Total here is 1480
A)
Favorable = less than 19 years old = 453 + 251 = 704
Required probability is 704/1480
= 0.47567567567
= 0.4757
B)
Favorable = more than 30 years old = 1480 - (251+453+165) = 611
Required probability is 611/1480
= 0.41283783783
= 0.4128

Why is my P-value wrong?
Suppose that Michael reads somewhere on the Internet that, on average, middle-aged people between 45 and 65 years old visit 12 different websites per day on weekend days. Michael knows that he cannot trust everything he reads on the Internet, so he decides to conduct his own study. He believes that the middle-aged people in his community visit more than 12 websites per day. He surveys a random sample of 15 middle-aged people in his...
