Chapter 5: Q4 (page 209)

Notation of 0+ Using the same survey from Exercise 3, the probability of randomly selecting 30 of the 1009 consumers and getting exactly 24 who are comfortable with the drones is represented as 0+. What does 0+ indicate? Does 0+ indicate that it is impossible to get exactly 24 consumers who are comfortable with the drones?

Short Answer

Expert verified

0+ indicates that it is unlikely that out of 30 consumers selected, exactly 24 consumers are comfortable with the drones,

0+ does not indicate that it is impossible to get exactly 24 consumers who are comfortable with the drones.

Step by step solution

01

Given information

The probability ofselecting 30 of 1009 consumers and getting exactly 24 who are comfortable with the drones is represented as 0+.

02

Meaning of 0+ 

If a probability value is represented as 0+, it means that the probability is very close to 0, and it is highly unlikely that the event will happen.

Thus, it can be said that it is unlikely that out of 30 consumers selected, exactly 24 consumers are comfortable with the drones,

0+ does not indicate that the event is impossible to occur. It says that the event is highly unlikely to take place.

Therefore, 0+ does not indicate that it is impossible to get exactly 24 consumers who are comfortable with the drones.

In Exercises 15鈥�20, assume that random guesses are made for eight multiple choice questions on an SAT test, so that there are n = 8 trials, each with probability of success (correct) given by p = 0.20. Find the indicated probability for the number of correct answers.

Find the probability that at least one answer is correct.

Whitus v. Georgia In the classic legal case of Whitus v. Georgia, a jury pool of 90 people was supposed to be randomly selected from a population in which 27% were minorities. Among the 90 people selected, 7 were minorities. Find the probability of getting 7 or fewer minorities if the jury pool was randomly selected. Is the result of 7 minorities significantly low? What does the result suggest about the jury selection process?

In Exercises 21鈥�24, assume that when adults with smartphones are randomly selected, 54% use them in meetings or classes (based on data from an LG Smartphone survey).

If 10 adult smartphone users are randomly selected, find the probability that at least 8 of them use their smartphones in meetings or classes.

Ultimate Binomial Exercises! Exercises 37鈥�40 involve finding binomial probabilities, finding parameters, and determining whether values are significantly high or low by using the range rule of thumb and probabilities.

M&Ms Data Set 27 鈥淢&M Weights鈥� in Appendix B includes data from 100 M&M candies, and 19 of them are green. Mars, Inc. claims that 16% of its plain M&M candies are green. For the following, assume that the claim of 16% is true, and assume that a sample consists of 100 M&Ms.

a. Use the range rule of thumb to identify the limits separating values that are significantly low and those that are significantly high. Based on the results, is the result of 19 green M&Ms significantly high?

b. Find the probability of exactly 19 green M&Ms.

c. Find the probability of 19 or more green M&Ms.

d. Which probability is relevant for determining whether the result of 19 green M&Ms is significantly high: the probability from part (b) or part (c)? Based on the relevant probability, is the result of 19 green M&Ms significantly high?

e. What do the results suggest about the 16% claim by Mars, Inc.?
