Question

Transcribed Image Text: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 α = 0.05.
Click the icon to view the heights of the candidates.
The linear correlation coefficientis r =
(Round to three decimal places as needed.)
Determine the null and alternative hypotheses.
Ho: P
H₁: p

Opponent 185 179 186 174 176 178 181 180 188 175 173 188 186 170
Because the P-value of the linear correlation coefficient is
the heights of winning presidential candiates and the heights of their opponents.
Should we expect that there would be a correlation?

OA. No, because height is the main reason presidential candidates are nominated.
OB. No, because presidential candidates are nominated for reasons other than height.
C. Yes, because height is the main reason presidential candidates are nominated.
D. Yes, because presidential candidates are nominated for reasons other than height.

There is statistically insignificant evidence to conclude that there is a correlation between the amount of time customers spend at the store and the amount of money that they spend at the store. Thus, the use of the regression line is not appropriate.
