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 reading the stories, the students listed as many facts as they could recall. The following data were recorded. This a multiple choice question!

        Before          After
          10                  15
          12                  14
          14                  17
          16                  17
          12                  20


The degrees of freedom for this sample are                            [ Select ]                       ["8", "5", "6", "4", "2.132", "2.776", "2.306", "1.860", "-3.106", "3.106", "-3.062", "3.602", "reject", "fail to reject", "may affect study habits", "does not affect study habits"]         

The two tailed critical value at an alpha level of .05 is                             [ Select ]                       ["8", "5", "6", "4", "2.132", "2.776", "2.306", "1.860", "-3.106", "3.106", "-3.062", "3.602", "reject", "fail to reject", "may affect study habits", "does not affect study habits"]         

The obtained value of the statistic calculated for this sample is                             [ Select ]                       ["8", "5", "6", "4", "2.132", "2.776", "2.306", "1.860", "-3.106", "3.106", "-3.062", "3.602", "reject", "fail to reject", "may affect study habits", "does not affect study habits"]         

My decision is to                             [ Select ]                       ["8", "5", "6", "4", "2.132", "2.776", "2.306", "1.860", "-3.106", "3.106", "-3.062", "3.602", "reject", "fail to reject", "may affect study habits", "does not affect study habits"]       the null hypothesis

Based on this data I conclude that the course                             [ Select ]                       ["8", "5", "6", "4", "2.132", "2.776", "2.306", "1.860", "-3.106", "3.106", "-3.062", "3.602", "reject", "fail to reject", "may affect study habits", "does not affect study habits"]

1. A questionnaire about study habits was given to a random sample of students taking a large introductory statistics class. Students were asked if they studied most nights in a week: yes or no. The results are that the sample proportion of students who answered “yes” (?̂) was 0.4. Consider the same scenario as in Problem 1. a) Calculate a confidence interval for sample size n = 1000, ?̂= 0.4, and the following confidence levels: 80%, 90%, and 99%. You...

In a statistics class, 8 students took their pulses before and after an exam. The pulse rates (beats per minute) of the students before and after the exam were obtained separately and are shown in the table. Treat this as though it were a random sample of statistics students. Test the hypothesis that the mean of statistics students' pulse rates is higher after an exam using a significance level of 0.05. Do the 5-step hypothesis test and submit an image...

In a study of habits of undergraduate students, a researcher sampled 53 students and found that the mean number of classes missed over the course of a school year was 18. Assume the population standard deviation, σ = 5.7. (5 points) Calculate the 95% confidence interval for the mean number of classes missed during the school year by undergraduate students. (2 points) If the researcher had sampled 75 students, would the margin of error be larger or smaller? (2 points)...

As our module reading highlights, applying test-taking skills involves what students do before, during and after the test. It includes managing test anxiety, becoming familiar with types of test questions, and using tests as a learning tool. Think about these components as you review your process in applying test-taking skills. Share responses to the following questions or statements: Explain how one or two of these suggestions for managing test anxiety can help you manage stress in test-taking and in a...
