Last year, a reporter wrote an article about the holidays. For the article, the reporter randomly sampled 20 households in Pine Valley and asked each resident how many days before Christmas they had put up their decorations. The mean was 17.4 days and the standard deviation was 3.8 days. Because of the pandemic the reporter believes that people are planning to decorate for the holidays earlier this year and leave their decorations up longer. The reporter randomly sampled 15 households this year and asked how many days before Christmas they planned to put up their holiday decorations.This year, the mean was 20.6 days and the standard deviation was 4.7 days. Can you show that the reporter is correct at the 0.05 level of significance?
