Welcome

## 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) Tip (dollars) 30.57            3.29 48.03            7.80 82.67            7.99 91.97            9.20 67.30            7.28 93.60           13.58

The linear correlation coefficient r is __​______.
(Round to three decimal places as​ needed.)

Determine the null and alternative hypotheses.
Ho​: ρ(1)____________ ________________
H1​: ρ(2)___________  ________________
(Type integers or decimals. Do not​ round.)

The test statistic is _________. ​
(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 (3) ___________the significance​ level, there (4)____________ sufficient evidence to support the claim that there is a linear correlation between bill amounts and tip amounts.

If everyone were to tip with the same​ percentage, then r = ________ .
​(Round to three decimal places as​ needed.)
