### 6.2#### 7) Use the "Beach Visitors" scatterplot to answer the questions that follow:**a) Identify the explanatory and response variables.****b) Estimate the correlation coefficient for the graph.****c) Describe what the scatterplot shows. (remember to describe the form, direction, strength, and any outliers)**---#### Scatterplot Explanation:**Title:** Beach Visitors- **X-axis (Horizontal):** Average Daily Temperature (°F), ranging from 80°F to 96°F.- **Y-axis (Vertical):** Number of Visitors, ranging from 75 to 600.**Description of the Scatterplot:**The scatterplot displays a positive relationship between the Average Daily Temperature (°F) and the number of Beach Visitors. As the temperature increases, the number of visitors also increases. The points on the plot suggest a positive correlation, where higher temperatures correspond to a higher number of visitors. The data appears to be spread out in an upward trend with no significant outliers visible.---Note: This is a transcription of the provided material with a detailed explanation of the scatterplot contained within the image.

The distances are in miles, the times are in minutes, the fares are in dollars, and the tips are in dollars. Is there sufficient evidence to conclude that there is a linear correlation between the time of the ride and the tip amount? Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r.
