Answer 1

Question

Chapter 9, Problem 1E

(a)

To determine

To explain is there a clear pattern and describe the trend.

(a)

Expert Solution

Answer to Problem 1E

Yes.

Explanation of Solution

The researcher wants to know that is the age of women get married has changed over the past years or not. The scatterplot given in the question shows the trend in age at first marriage for American women. From looking at the scatterplot given in the question, we can say that the relationship between women age with years is linear until 1945 and then becomes non-linear until 1970 and then again become linear until end year. So, there is a clear pattern of the scatterplot of women’s age at first marriage with years.

(b)

To determine

To explain is the association strong or not.

(b)

Expert Solution

Answer to Problem 1E

Yes, it is strong.

Explanation of Solution

The researcher wants to know that is the age of women get married has changed over the past years or not. The scatterplot given in the question shows the trend in age at first marriage for American women. By looking at the scatterplot, we can say that the association is strong as the points in the scatterplot shows the clear pattern and are in upward direction.

(c)

To determine

To explain is the association high or not.

(c)

Expert Solution

Answer to Problem 1E

No, it is not high.

Explanation of Solution

The researcher wants to know that is the age of women get married has changed over the past years or not. The scatterplot given in the question shows the trend in age at first marriage for American women. From looking at the scatterplot of women’s age at first marriage with years we can say that the association is not high as the graph is non-linear between the years.

(d)

To determine

To explain is the linear model appropriate or not.

(d)

Expert Solution

Answer to Problem 1E

No, it is not appropriate.

Explanation of Solution

The researcher wants to know that is the age of women get married has changed over the past years or not. The scatterplot given in the question shows the trend in age at first marriage for American women. The linear model is not appropriate because the graph has the curve in it so, a linear model would not give accurate results.
