Chapter 2: Q 74. (page 141)

Normal to be foreign-born? The histogram displays the percent of foreign-born residents in each of the 50 states.12 Explain why this distribution of the percent of foreign-born residents in the states is not approximately Normal.

Short Answer

Expert verified

The distribution has been skewed to the right instead of roughly symmetric.

Step by step solution

01

Given information

02

Concept

A dot plot is a graphical display of data using dots.

03

Explanation

The symmetric nature of the Normal distribution is one of its characteristics.

The histogram's distribution is skewed to the right; we can also see that most of the dots in the histogram are to the left, with a tail of less common values to the right.

We know that

The Normal distribution should be symmetric.

And

This distribution has been skewed to the right.

We can say

This distribution is not approximately the Normal distribution.

Mean and median The figure displays two density curves that model

different distributions of quantitative data. Identify the location of the mean and median by letter for each graph. Justify your answers.

Step right up! Refer to Exercise 22 Suppose that the distances from the tops of the students鈥� heads to the ground are converted from inches to feet (note that 12in.=1ft).

a. What shape would the resulting distribution have? Explain your answer.

b. Find the mean of the distribution of distance in feet.

c. Find the standard deviation of the distribution of distance in feet.

Travel time (1.2) The dot-plot displays data on students鈥� responses to the question 鈥淗ow long does it usually take you to travel to school?鈥� Describe the distribution.

Comparing bone density Refer to Exercise 17 Judy鈥檚 friend Mary also had the bone density in her hip measured using DEXA. Mary is 35 years old. Her bone density is also reported as 948g/cm2 but her standardized score is z=0.50 The mean bone density in the hip for the reference population of 35-year-old women is 944grams/cm2

a. Whose bones are healthier for her age: Judy鈥檚 or Mary鈥檚? Justify your answer.

b. Calculate the standard deviation of the bone density in Mary鈥檚 reference population. How does this compare with your answer to Exercise 17(b)? Are you surprised?

b. The median is at the red line and the mean is at the yellow line.

c. The mode is at the red line and the median is at the yellow line.

d. The mode is at the yellow line and the median is at the red line.

e. The mode is at the red line and the mean is at the yellow line.
