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 alpha e quals 0.01 . If everyone were to tip with the same percentage, what should be the value of r? a. The linear correlation coefficient is r equals (Round to three decimal places as needed.) b. The test statistic is t equals (Round to two decimal places as needed.) c. The P-value is (Round to three decimal places as needed.)

Transcribed Image Text:**Table of Bills and Corresponding Tips**
This table displays a series of bills in dollars along with the corresponding tips. The data is useful for understanding tipping behavior in relation to bill amounts.
| **Bill (dollars)** | 33.44 | 53.45 | 87.46 | 89.25 | 60.34 | 109.78 |
|-------------------|-------|-------|-------|-------|-------|--------|
| **Tip (dollars)** | 6.55 | 10.40 | 15.65 | 16.21 | 7.10 | 12.58 |
- **Bill (dollars):** Represents the total amount of the bill before the tip.
- **Tip (dollars):** Represents the amount of money given as a tip.
This data can be analyzed to find the tipping percentage or to study patterns in tipping behavior.
