The correct statement is:

There is a positive association between the number of years that have passed between 1974 and the price of a movie ticket.

This is true because the slope of the line of best fit (0.16) is positive, indicating that as the years increase since 1974, the price of a movie ticket also tends to increase.

To clarify the other options:

  • The slope of the line of best fit (0.16) indicates that movie ticket prices tend to increase by about $0.16 per year, not $1.52 or $0.25.
  • The statement about a decrease in price is incorrect, as it suggests a negative slope, which is not the case here.

So the positive association is the only accurate statement among the options.
