Five students were tested before and after taking a class to improve their study habits. They were given articles to read which contained a known number of facts in each story. After the story each student listed as many facts as he/she could recall. The following data was recorded. What do you conclude using a = 0.052 tail? A) reject H₀; the class appeared to improve study habits B) retain H₀; the class had no effect on study habits C) retain H₀; we cannot conclude that the class improved study habits D) accept H₀; the class appeared to improve study habits

To determine the conclusion using a significance level of 0.052 tail, we need to conduct a one-tailed paired t-test on the difference between the number of facts each student remembered before and after the class. Based on the results of the t-test, if the p-value is less than or equal to 0.052, we can reject the null hypothesis (H₀) and conclude that the class appeared to improve study habits. After performing the t-test, if the p-value is greater than 0.052, we cannot reject the null hypothesis and cannot conclude that the class improved study habits. In this particular case, the question does not provide the results of the t-test or the p-value obtained. So, we cannot determine the correct answer without this information. However, assuming that the p-value is less than or equal to 0.052, the correct answer would be A.
