A taxi driver records the time required to complete various trips and the distance for each trip.

The best-fit line is given by the equation \(y = 0.467x + 0.417\), where \(y\) represents the distance in miles and \(x\) represents the time for the trip in minutes.

1. Use the best-fit line to estimate the distance for a trip that takes 20 minutes. Show your reasoning.
2. Use the best-fit line to estimate the time for a trip that is 6 miles long. Show your reasoning.

Data is collected about the number of wins and losses by a random sample of teams with an animal mascot and those with another kind of mascot. The column relative frequencies are shown in the table. Given the information in the table, is there an association between the variables? Explain your reasoning.

A random selection of indoor and outdoor pool managers are surveyed about the number of people in each age group that swim there. Results from the survey are displayed in the two-way table. Given the data, does there appear to be an association between pool type and age group? Explain your reasoning. 

Data from a random sample of people are collected about how they watch movies in the genres of action or mystery. Which value would best fit in the missing cell to suggest there is no association between the genre and how the movies are watched?
