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).

Sampling senators The two-way table describes the members of the U.S. Senate in a recent year. Suppose we select a senator at random. Consider events D: is a democrat, and F: is female.

(a) Find P(D | F). Explain what this value means.

(b) Find P(F | D). Explain what this value means.

Waiting to park (1.3) Do drivers take longer to leave their parking spaces when someone is waiting? Researchers hung out in a parking lot and collected

some data. The graphs and numerical summaries below display information about how long it took drivers to exit their sp\aces.

(a) Write a few sentences comparing these distributions.

(b) Can we conclude that having someone waiting causes drivers to leave their spaces more slowly? Why or why not?

Make a two-way table that displays the sample space.

Brushing teeth, wasting water? A recent study reported that fewer than half of young adults turn off the water while brushing their teeth. Is the same true for teenagers? To find out, a group of statistics students asked an SRS of 60 students at their school if they usually brush with the water off. How many

students in the sample would need to say 鈥淣o鈥� to provide convincing evidence that fewer than half of the students at the school brush with the water off? The Fathom dot plot below shows the results of taking 200 SRSs of 60 students from a population in which the true proportion who brush with the

water off is 0.50.

(a) Suppose 27 students in the class鈥檚 sample say 鈥淣o.鈥� Explain why this result does not give convincing evidence that fewer than half of the school鈥檚 students brush their teeth with the water off.

(b) Suppose 18 students in the class鈥檚 sample say 鈥淣o.鈥� Explain why this result gives strong evidence that fewer than 50% of the school鈥檚 students brush

their teeth with the water off.

Cold weather coming to A TV weather man, predicting a colder-than-normal winter, said, 鈥淔irst, in looking at the past few winters, there has been a lack of

really cold weather. Even though we are not supposed to use the law of averages, we are due.鈥� Do you think that 鈥渄ue by the law of averages鈥� makes sense in talking about the weather? Why or why not?
