The Motion Picture Association claims that an average American sees 3.9 movies at the theater each year. A curious student randomly selects a sample of 30 students from their school and finds that people in the sample have seen an average of 4.5 movies with a standard deviation of 1.2 movies. Does this sample provide evidence that people are attending the movies more often? Provide a complete significance test using `\alpha` = 0.01 to support your answer.
