Transcribed Image Text:Listed below are amounts of bills for dinner and the amounts of the tips that were left. 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. Use a significance level of a = 0.05. If everyone were to tip with the same percentage, what should be the value of r?

✔
The linear correlation coefficient is r=
(Round to three decimal places as needed.)
Determine the null and alternative hypotheses.
Ho: P
H₁: p
(Type integers or decimals. Do not round.)
The test statistic is t =
(Round to two decimal places as needed.)
The P-value is
(Round to three decimal places as needed.)
Because the P-value of the linear correlation coefficient is
If everyone were to tip with the same percentage, then r =
