1. Which variables can be classified as quantitative? Which variables can be classified as qualitative?
2. What is the level of measurement for gross sales (In millions)
3. Calculate the mean and standard deviation of the Length variable for the 35 movies. (Rounded to two decimal places.) Interpret your results
4.Create a chart of Title vs Length. Paste the chart into the document and discuss what the chart is showing. Are there any outliners? If so, which movie(s)?
5. Create a frequency distribution of the viewer ratings using 5 classes. Your first class should be 0 -2
6. Using the frequency distribution created in problem 5, find the probability of the viewer rating between 6.3 and 8.3
7. Using the average and standard deviation for the Length variable from problems #3, find the probability that the length of the 35 movies is less than 120 minutes. Assuming the distribution is normally distributed. Interpret your results.
8. Using the average and standard deviation for the Length variable from problem #3. Find the length of time, x, that corresponds to a z-score of 1.96. Interpret your results
9. Find a point estimate of the mean, u, for gross sales of the 35 movies
