The linear correlation coefficient is
r=0.9780.978.


​(Round to three decimal places as​ needed.)

Determine the null and alternative hypotheses.




H0​:ρ   ____   ______




H1​:ρ  _____  _______






(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



less than or equal to:





the significance​ level, there is:

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.)

Extracted 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 = 0.01. If everyone were to tip with the same percentage, what should be the value of r? Bill (dollars) Tip (dollars) 33.70 47.69 89.22 12.86 95.30 61.72 102.82 o 5.71 6.07 16.11 10.26 17.49 Construct a scatterplot. Choose the correct graph below. OA. O B. Oc.
