9. In 2018, a poll in San Francisco reported that 58% of internet users had ordered food delivery to their homes. After the 2020 pandemic another poll was conducted of 400 San Franciscans asking whether they had ordered food for home delivery. 64% said Yes. Does this sample provide sufficient evidence to conclude that home food delivery changed during the pandemic? Sample data are provided in the Excel dataset FoodDeliveryxlsx. Use the data "FoodDelivery" on the first tab labeled "FoodDelivery". If you use JASP, you will need to export the first sheet as a CSV. Use a Binomial Test in JASP to determine whether the proportion of food delivery changed at the .05 level of significance Select the appropriate statistic Test: _______________________________ State the Null and the Alternative Hypothesis Null: H0: _____________ Alt: H1: _____________ Select a level of significance Tails: ___________-tail test, = _________ CV: 1.96 Calculate the Statistics Stats: p= ________, 95% CI[__________, __________] Make the decision! Decision: Reject the null or fail to reject? _______________________________________________________ Did food ordering change? __________________________________________________________ Did food ordering increase, decrease, or stay the same? _________________________________
