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 α=0.05. If everyone were to tip with the same percentage, what should be the value of r? A. The linear correlation coefficient is r= (Round to three decimal places as needed.) B. The test statistic is t= (Round to two decimal places as needed.) C. The P-value is (Round to three decimal places as needed.)
