PLEASE HELP WITH THE LAST PART OF THIS PROBELM

Listed below are amounts of court income and salaries paid to the town justices. All amounts are in thousands of dollars. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using

α=0.05.

Is there sufficient evidence to conclude that there is a linear correlation between court incomes and justice salaries? Based on the results, does it appear that justices might profit by levying larger fines?

Court Income	66.0	402.0	1567.0	1131.0	270.0	253.0	110.0	154.0	32.0
Justice Salary	29	45	91	57	46	61	26	27	17

What are the null and alternative hypotheses?

A scatterplot has a horizontal scale labeled “Court Income” from 0 to 1600 in intervals of 200 and a vertical scale labeled “Justice Salary” from 0 to 100 in intervals of 10. Nine points are plotted. Seven of the points loosely follow the pattern of a line passing through the points (147, 35) and (1276, 89). The plotted points (137, 13) and (1315, 14) are outliers.

A scatterplot has a horizontal scale labeled “Court Income” from 0 to 1600 in intervals of 200 and a vertical scale labeled “Justice Salary” from 0 to 100 in intervals of 10. Nine plotted points follow the pattern of a line that falls from left to right passing through the points (216, 84) and (1413, 43).

A scatterplot has a horizontal scale labeled “Court Income” from 0 to 1600 in intervals of 200 and a vertical scale labeled “Justice Salary” from 0 to 100 in intervals of 10. Nine points are plotted. Eight of the plotted points follow the pattern of a line rising from left to right passing through the points (32.0, 17) and (1567.0, 91). An outlier is plotted at (253.0, 61).

Your answer is correct.

Eight of the plotted points loosely follow the pattern of a line falling from left to right passing through the points (264, 84) and (1473, 17). An outlier is plotted at (421, 24)..

The linear correlation coefficient is

r=0.8670.867.

(Round to three decimal places as needed.)

The test statistic is

t=4.6104.610.

(Round to three decimal places as needed.)

The P-value is

0.0010.001.

(Round to three decimal places as needed.)

Because the P-value is

less

than the significance level

0.05,

there

sufficient evidence to support the claim that there is a linear correlation between court incomes and justice salaries for a significance level of

α=0.05.
