Chapter 5: Q T5.7. (page 337)

What is the probability that a student has a GPA under2.0 given that he or she has skipped many classes? (a)0.080(b)0.281(c)0.285(d)0.314(e)0.727

Short Answer

Expert verified

The correct option is (e)0.727

Step by step solution

01

Step 1. Given

The table is:

02

Step 2. Concept

The probability of an event=numberoffavourableoutcomestotalnumberofoutcomes

03

Step 3. Calculation

Given that she has skipped multiple classes, the likelihood that she has a GPA below 2.0 is calculated as follows:

P(<2.0||many)=P(<2.0andmany)P(Many)=8010001101000=0.727

As a result, 0.727 is the required probability.

As a result, the best solution is (e).

Languages in Canada Canada has two official languages, English and French. Choose a Canadian at random and ask, “What is your mother tongue?”

Here is the distribution of responses, combining many separate languages from the broad Asia/Pacific region:6Language: English French Asian/Pacific Other Probability: 0.630.220.06?

(a) What probability should replace “?” in the distribution? Why?

(b) What is the probability that a Canadian’s mother tongue is not English?

(c) What is the probability that a Canadian’s mother tongue is a language other than English or French?

Free downloads? Illegal music downloading has become a big problem: 29% of Internet users download music files, and 67% of downloaders say they

don’t care if the music is copyrighted.15 What percent of Internet users download music and don’t care if it’s copyrighted? Write the information given in terms of probabilities, and use the general multiplication rule.

Teachers and college degrees Select an adult at random. Define events A: a person has earned a college degree, and T: person’s career is teaching. Rank the following probabilities from smallest to largest. Justify your answer.

Mac or PC? A recent census at a major university revealed that40% of its students primarily used Macintosh computers (Macs). The rest mainly used

PCs. At the time of the census, 67% of the school’s students were undergraduates. The rest were graduate students. In the census, 23% of respondents were graduate students who said that they used PCs as their

main computers. Suppose we select a student at random from among those who were part of the census.

(a) Assuming that there were 10,000 students in the census, make a two-way table for this chance process.

(b) Construct a Venn diagram to represent this setting.

(c) Consider the event that the randomly selected student is a graduate student who uses a Mac. Write this event in symbolic form using the two events of interest that you chose in (b).

(d) Find the probability of the event described in (c). Explain your method.

Recycling Do most teens recycle? To find out, an AP Statistics class asked an SRS of 100 students at their school whether they regularly recycle. How many students in the sample would need to say “Yes” to provide convincing evidence that more than half of the students at the school recycle? The Fathom dot plot below shows the results of taking 200 SRSs of 100 students from a population in which the true proportion who recycle is 0.50.

(a) Suppose 55 students in the class’s sample say “Yes.” Explain why this result does not give convincing evidence that more than half of the school’s students recycle.

(b) Suppose 63 students in the class’s sample say “Yes.” Explain why this result gives strong evidence that a majority of the school’s students recycle.
