QUESTION 12 In the video game Animal Crossing: New Horizons, you can catch and sell both fish and sea creatures. Alison learns that sea creatures sell for a mean of u = 3,345 bells with a standard deviation of o = 3,684 bells ("bells" is the currency in the game). Alison suspects that fish will sell for more money than sea creatures will, so she decides to conduct a hypothesis test at the a = 0.01 level with %3D %3D Họ: µ= 3,345 bells H1: p > 3,345 bells She finds a sample of 64 fish and computes their mean price to be 3,527 bells. a. Determine the standard error to the nearest thousandth. Ox = Work: b. Determine the z-score to the nearest hundredth. Z = Work: c. Identify the image below that best represents the standard normal curve you drew for this problem. A В C
