Suppose a social scientist wants to know the effects of gender upon film preferences. She samples fifty men and women and asks them to mark their preference between to genres: documentaries and dramas. She then constructs a two-way frequency table as shown:

What is the relative probability of men who prefer dramas?

Use technology to find the least squares regression equation for the following data set.

Market analysts for an automotive company randomly sampled five hundred new car buyers using a simple survey. This survey recorded the preferences of future consumers. The analysts documented several preferences in the same survey: engine size (i.e. an eight cylinder—V8—or a six cylinder—V6) and paint color. The data are present in the provided table.

What of the following correctly calculates the probability intersection future consumers that will want a car that is Black Pearl and has a V8?

A researcher for a motor vehicle company wants to observe the relationship between a vehicle's weight and mileage. He decides to investigate 40 vehicles and tabulates the following data.

Afterwards, he plotted the data into a scatter plot and fitted a trendline to the graph.

Which of the following is the best conclusion that can be made about the data's linearity?
