Media periodically discuss the issue of heights of winning presidential candidates and heights of their main opponents. The accompanying table lists the heights (cm) from several recent presidential elections. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Should we expect that there would be a correlation? Use a significance level of a = 0.05. E Click the icon to view the heights of the candidates. . Construct a scatterplot. Choose the correct graph below. OB. OC. OD.

Thus, the alternative hypothesis is
ρ≠0.
The null hypothesis must express equality. The correct null and alternative hypotheses are given below.
For this exercise, use the same technology output that was used to calculate the correlation coefficient to find the t test statistic, rounding to two decimal places.
Use the same technology output that was used to calculate the correlation coefficient and test statistic to find the P-value, rounding to three decimal places.
