Chapter 5: Q. 1 (page 308)

Another commercial If Aaron tunes into his favorite radio station at a

randomly selected time, there is a0.20 probability that a commercial will be playing.

a. Interpret this probability as a long-run relative frequency.

b. If Aaron tunes into this station at 5randomly selected times, will there be exactly one

time when a commercial is playing? Explain your answer.

Short Answer

Expert verified

a) The relative frequency (which is the number of desired results divided by the number of total outcomes) of event A will be a/100

b) the interpretation is that a commercial will be playing roughly 20% of the time he tunes in to his favourite station over a long period of time.

Step by step solution

01

Part (a) Step 1: Given information

We have to interpret this probability as a long-run relative frequency.

02

Part (a) Step 2: Explanation

The relative frequency (which is the number of desired results divided by the number of total outcomes) of event A will be a/100 across a large number of experiments if the probability of outcome A is a percent.

03

Part (b) Step 1: Given information

We have to tell that will there be exactly one time when a commercial is playing.

04

Part (b) Step 2: Explanation

When dials in to his preferred station, there is a 0.2chance that he will hear an advertisement.

As a result, the interpretation is that a commercial will be playing roughly 20%of the time he tunes in to his favourite station over a long period of time.

Smartphone addiction? A media report claims that 50%of U.S. teens with smartphones feel addicted to their devices. A skeptical researcher believes that this figure is too high. She decides to test the claim by taking a random sample of 100U.S. teens who have smartphones. Only 40of the teens in the sample feel addicted to their devices. Does this result give convincing evidence that the media report鈥檚 50%claim is too high? To find out, we want to perform a simulation to estimate the probability of getting 40or fewer teens who feel addicted to their devices in a random sample of size 100from a very large population of teens with smartphones in which 50% feel addicted to their devices.

Let 1= feels addicted and 2= doesn鈥檛 feel addicted. Use a random number generator to produce 100random integers from 1to 2. Record the number of 1鈥檚 in the simulated random sample. Repeat this process many, many times. Find the percent of trials on which the number of 1鈥檚 was40 or less.

Roulette An American roulette wheel has 38 slots with numbers 1through36,0,and 00, as shown in the figure. Of the numbered slots, 18are red, 18are black, and 2鈥攖丑别 0and 00鈥攁re green. When the wheel is spun, a metal ball is dropped onto the middle of the wheel. If the wheel is balanced, the ball is equally likely to settle in any of the numbered slots. Imagine spinning a fair wheel once. Define events B: ball lands in a black slot, and E: ball lands in an even-numbered slot. (Treat0and 00as even numbers.)

a. Make a two-way table that displays the sample space in terms of events Band E.

b. Find P(B)andP(E).

c. Describe the event 鈥�Band E鈥� in words. Then find the probability of this event.

d. Explain why P(BorE)鈮�P(B)+P(E). Then use the general addition rule to compute P(BorE).

Who鈥檚 pregnant? According to the Current Population Survey (CPS), 27%

of U.S. females are older than 55. The Centers for Disease Control and Prevention (CDC) report that 6% of all U.S. females are pregnant. Suppose that these results are accurate. If we randomly select a U.S. female, is P(pregnant and over 55) =(0.06)(0.27)=0.0162? Why or why not?

Mac or PC? A recent census at a major university revealed that60%of its students mainly used Macs. The rest mainly used PCs. At the time of the census, 67%of the school鈥檚 students were undergraduates. The rest were graduate students. In the census, 23%of respondents were graduate students and used a Mac as their main computer. Suppose we select a student at random from among those who were part of the census. Define events G: is a graduate student and M: primarily uses a Mac.

a. Find P(G 鈭� M). Interpret this value in context.

b. Consider the event that the randomly selected student is an undergraduate student and

primarily uses a PC. Write this event in symbolic form and find its probability.
