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 = 0.01. If everyone were to tip with the same​ percentage, what should be the value of​ r?

Bill​ (dollars)    31.62 52.20    90.36 99.42    60.70    100.52
Tip​ (dollars)    3.90    10.40    8.62 18.13 10.60    12.95
