Module 13 Project Name: _____________________ Post-Halloween Data Analysis SHOW YOUR WORK FOR EACH QUESTION! 1. According to AI, the average amount of money people in the U.S. spent on Halloween costumes in 2024 was $33.92. We want to see if this amount has changed for Halloween 2025. We will use a data set from a survey of 1,216 adults from the U.S. a. Write the null and alternative hypotheses. b. Check the condition(s) for the appropriate hypothesis test. c. Use Excel or StatCrunch to find the mean amount spent in 2025 for the of 1,216 people in the sample as well as the standard deviation of the data. (Instructions are below). Make sure to use the correct notation for it! Mean: Standard deviation: d. Find the test statistic from StatCrunch (instructions are below). If you don't have access to StatCrunch, only Excel, then you need to calculate the test statistic using the calculator. e. Draw and shade the corresponding area(s) for the test statistic/p-value. You can also copy if from StatCrunch or from the normal probability app. 2 f. Find the p-value using StatCrunch or the calculator or the normal applet. g. Make your conclusion in context using 5% significance
