Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…

Chapter 1, Problem 9P

Life Expectancy The average life expectancy in the United States has been rising steadily over the past few decades, as shown in the table.

  • (a) Make a scatter plot of the data.
  • (b) Find and graph the regression line.
  • (c) Use the linear model you found in part (b) to predict the life expectancy in the year 2006.
  • (d) Search live Internet or your campus library to find the actual 2006 average life expectancy. Compare to your answer in part (c).

(a)

Expert Solution
Check Mark
To determine

To graph: The scatter plot of the data.

Explanation of Solution

Graph:

Consider the Year as the x coordinates and average life expectancy as the y coordinates.

Let x = Year – 1920.

The scatter plots of the given data are shown below in Figure 1.

EBK PRECALCULUS: MATHEMATICS FOR CALCUL, Chapter 1, Problem 9P , additional homework tip 1

In Figure 1, all the points are plotted on the graph.

The year 1920 is corresponds to 0 and 2000 is corresponds to 80.

(b)

Expert Solution

To determine

To find: The regression line that represents the given data and draws the graph of the same.

Answer to Problem 9P

The regression line that represents the given data is y=0.2708x+57.10 .

Explanation of Solution

By the use of online calculator, the regression line for the given data obtained is y=0.2708x+57.10 , where average life expectancy is the y-intercept and year is the x-intercept.

Therefore, the regression line that represents the given data is y=0.2708x+57.10 .

The graph that represents the equation y=0.2708x+57.10 is shown below in Figure 1.

EBK PRECALCULUS: MATHEMATICS FOR CALCUL, Chapter 1, Problem 9P , additional homework tip 2

From Figure 2, the graph for the linear equation y=0.2708x+57.10 is a straight line.

(c)

Expert Solution

To determine

To find: The estimate life expectancy in the year 2006.

Answer to Problem 9P

The estimate life expectancy in the year 2006 is 80.4.

Explanation of Solution

Consider the year 2006.

From part (b), it is obtained that the linear equation that represents the given data is y=0.2708x+57.10 .

Substitute x = 2006 − 1920 in the above equation to compute the life expectancy in the year 2006.

y=0.2708(2006−1920)+57.10=0.2708(86)+57.10=23.2888+57.10=80.3888

Thus, the estimate life expectancy in the year 2006 is 80.4 years.

(d)

Expert Solution
Check Mark
To determine

To Compare: The estimate value with the actual value.

Explanation of Solution

By the use of internet, the actual life expectancy in United states in the year 2006 is 77.69 years.

From part (c), it is obtained that the estimate life expectancy in the year 2006 is 80.4 years.

It is observed that the actual life expectancy is less than the average life expectancy estimated by the use of linear model y=0.2708x+57.10 .
