The Hypotheses for this problem are:

H₀: μ₁ = μ₂

H₁: μ₁ μ₂

a) Find the p-value. Round answer to 4 decimal places.

Answer: ?

b) Choose the correct decision and summary based on the above p-value.

Reject H₀. There is no evidence that the average movie ticket sales in San Diego and Portland per week differ.

Do not reject H₀. There is no evidence that the average movie ticket sales in San Diego and Portland per week differ.

Reject H₀. There is evidence that the average movie ticket sales in San Diego and Portland per week differ.

Do not reject H_0. There is evidence that the average movie ticket sales in San Diego and Portland per week differ.

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.
