1. Vera Bradley, a U.S. handbag and luggage brand, recently surveyed a simple random sample of n = 320 customers who bought something from the newly launched winter collection. They would like to determine whether or not the mean age of the customers is below 35. If so, they will deliver a 2024 Spring collection catering to a younger crowd. Suppose they found that the sample mean was 34.7 years old and the population standard deviation was 4 years. What is the p-value associated with the test statistic?
