The table below includes data from taxi rides. 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 thatthere 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. Determine whetherthere is sufficient evidence to support a claim of linear correlation between the two variables. Use a significance level of α = 0.01.

The U.S. News & World Report collects information on colleges and universities including tuition cost and average starting salary of graduates. The correlation between these two variables is weak but positive. Suppose a particular college is at the 40th percentile of both tuition and average starting salary. Relative to all colleges at the 40th percentile of tuition, this means that graduates from this college...

A sociologist is studying the relationship between income and farm production in California’s Central Valley. She has data for each county, showing the average income and total farm production (in dollars) for that county. The correlation is 0.43. Does this give a fair estimate of the strength of the association between income and farm production? Explain why.
The accompanying table lists the ages of acting award winners matched by the years in which the awards were won. 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. Should we expect that there would be a correlation?
