Chapter 7: Q. 2.11 (page 489)

refer to the following graph. Here is a dotplot of the adult literacy rates in 177 countries in a recent year, according to the United Nations. For example, the lowest literacy rate was 23.6 %, in the African country of Burkina Faso. Mali had the next lowest literacy rate at 24.0 %.

The overall shape of this distribution is

a. clearly skewed to the right.

b. clearly skewed to the left.

c. roughly symmetric.

d. uniform.

e. There is no clear shape.

Short Answer

Expert verified

b. The overall shape of this distribution is clearly skewed to the left.

Step by step solution

01

Given Information

The graph is

02

Explanation for correct option

This graph has a very large side to the right and a very small side to the left. The distribution would be skewed to the left since it is tiny at the tail's end or on the left side and large at the head. As a result, the correct option is (b)

03

Explanation for incorrect option

a. clearly skewed to the right is not the correct answer.

c. roughly symmetric is not the correct answer.

d. uniform is not the correct answer.

e. There is no clear shape is not the correct answer.

The central limit theorem is important in statistics because it allows us to use a Normal distribution to find probabilities involving the sample mean if the

a. sample size is reasonably large (for any population).

b. population is Normally distributed (for any sample size).

c. population is Normally distributed and the sample size is reasonably large.

d. population is Normally distributed and the population standard deviation is known (for any sample size).

e. population size is reasonably large (whether the population distribution is known or not).

AP2.20 A grocery chain runs a prize game by giving each customer a ticket that may win a prize when the box is scratched off. Printed on the ticket is a dollar value ( \( 500, \) 100, \(25) or the statement "This ticket is not a winner." Monetary prizes can be redeemed for groceries at the store. Here is the probability distribution of the amount won on a randomly selected ticket:

Which of the following are the mean and standard deviation, respectively, of the winnings?

a. \) 15.00, \( 2900.00

b.\) 15.00, \( 53.85

c. \) 15.00, \( 26.93

d. \) 156.25,\( 53.85

e. \) 156.25, $ 26.93

Airline passengers get heavier In response to the increasing weight of airline passengers, the Federal Aviation Administration (FAA) told airlines to assume that passengers average 190 pounds in the summer, including clothes and carry-on baggage. But passengers vary, and the FAA did not specify a standard deviation. A reasonable standard deviation is 35 pounds. A commuter plane carries 30 passengers. Find the probability that the total weight of 30 randomly selected passengers exceeds 6000 pounds.
