Chapter 5: Q. 6 (page 309)

Keep on tossing The figure shows the results of two different sets of5000coin tosses.

Explain what this graph tells you about chance behavior in the short run and the long run.

Short Answer

Expert verified

In the short run, values will be different than the proportion of .5while in the long run, the probability of heads will be about0.5.

Step by step solution

01

Given information

We have been given the results of two different sets of 5000coin tosses.

We need to find out the chance behavior in the short run and the long run from the graph.

02

Explanation

In the short run due to different peaks present below and above the proportion of 0.5there is a variation in the result very much and due to this, it takes on values very different than a proportion of 0.5.

In the long run, the proportion always tends to be about 0.5and this implies that the long-run frequency is about 0.5so the probability of heads will be about0.5.

Household size In government data, a household consists of all occupants of a dwelling unit. Choose an American household at random and count the number of people it contains. Here is the assignment of probabilities for the outcome. The probability of finding 3people in a household is the same as the probability of finding 4people.

a. What probability should replace 鈥�?鈥� in the table? Why?

b. Find the probability that the chosen household contains more than 2people.

point shots. Explain what this graph tells you about chance behavior in the short run and

long run.

Liar, liar! Sometimes police use a lie detector test to help determine whether a suspect is

telling the truth. A lie detector test isn鈥檛 foolproof鈥攕ometimes it suggests that a person is

lying when he or she is actually telling the truth (a 鈥渇alse positive鈥�). Other times, the test

says that the suspect is being truthful when he or she is actually lying (a 鈥渇alse negative鈥�).

For one brand of lie detector, the probability of a false positive is 0.08.

a. Explain what this probability means.

b. Which is a more serious error in this case: a false positive or a false negative? Justify

your answer.

Languages in Canada Canada has two official languages, English and French. Choose a Canadian at random and ask, 鈥淲hat is your mother tongue?鈥� Here is the distribution of responses, combining many separate languages from the broad Asia/Pacific region

b. What is the probability that the chosen person鈥檚 mother tongue is not English?

c. What is the probability that the chosen person鈥檚 mother tongue is one of Canada鈥檚 official languages?
