Question

12. In a study of memory recall, 5 people were given 10 minutes to memorize a list of 20 words. Each was asked to list as many of the words as he or she could remember both 1 hour and 24 hours later. The result is shown in the following table. Assume we want to use a 0.05 significance level in your analysis. The research question is: Do students recall significantly more words after 1 hour than after 24 hours of exposure to the words in the memory test?” Video Link: https://youtu.be/wy8GVt7Ityk Data: # words recalled # words recalled Subject 1 hour later 24 hours later 1 13 13 2 18 14 3 12 11 4 15 14 5 11 11 This question will be a four-part question (i.e., Parts A, B, C and D). Part A) Identify the null and alternative hypothesis. Part B) Use Excel Data Analysis and run the T-Test: Paired 2 Sample for Means and copy the output below and identify the p value for the one tailed test. Part C) Is your p-value significant i.e., less than the 0.05 significance test level? Part D) What can you conclude based on your p value analysis and hypothesis testing?
