Question

Disney is trying to decide if they should make another Avengers' movies because they believe that non-Avengers movies do not perform as well. They want test whether non-Avengers movies make less than Avengers movies. To do so they take a random sample of marvel movies. Assume that Avengers movies the average gross for a film was $1,941 million dollars.

Assume that this follows a normal distribution. Find the confidence interval at the 95% confidence level. Include intermediate steps to receive partial credit.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
