2. A new pill is touted to improve the memory retention capability of teenagers aging 13 to 16 years old. To test thisclaim, twenty teenagers of the same age range are randomly picked to read the first two chapters of the book "HarryPotter and the Philosopher's Stone" after which they are asked to enumerate the number of verbs they rememberfrom those chapters. Then they are given the new pill to be taken once daily for 7 days. At the end of 7 days, theyare asked to read the same two chapters and enumerate the number of verbs they remember. The results aretabulated below:Number of verbs rememberedNumber of verbs rememberedТeenbefore taking the pill (X1)after taking the pill (X2)16.71031415479.812410757839.9910101012116.128913410148815913166.9.171113187619208At the 1% level of significance, what can you conclude?

In a recent study, 50 males used a new weight-loss supplement, and all but 15 of them experienced weight loss after two weeks. In the same study, 100 females used the same supplement, and all but 22 of them experienced weight loss after two weeks. Fill in the blanks below to make the most reasonable statement possible. The new weight-loss supplement was less effective on ▼(Choose one) in the study. That is because only % of them lost weight after two weeks, whereas % of the ▼(Choose one) lost weight after two weeks.
A child development specialist is interested in learning if a new learning program increases students’ memory. 15 Subjects learned a list of 50 words. Learning performance was measured using a recall test. Students were initially tested and then tested again after using the new program. Below is the number of words remembered by each student.

Scientists have found a way to distinguish chronic-fatigue syndrome (CFS) from post-treatment Lyme disease by different proteins in a patient's spinal fluid. In a study of 4334 patients, the results to the right were found. (a) How many had the protein for Lyme only? (b) How many had the normal protein only? (c) How many had none of the proteins? 1654 had the protein for normal patients, CFS, and post-treatment Lyme disease; 1754 had the protein for CFS and Lyme; 820 had the protein for CFS only; 2660 had the protein for CFS; 1759 had the normal protein as well as the one for Lyme; 2625 had the protein for Lyme; 2648 had the normal protein. (a) There were 766 patients who only had the protein for Lyme. (Type a whole number.) (b) There were patients who only had the normal protein. (Type a whole number.)

You are interested in finding out if kangaroo rats that have been offered food ad lib(unlimited food) for the previous 24 hours store a different amount of food in their pouches than kangaroo rats that have been starved for 24 hours. You take 8 kangaroo rats and starve them for 24 hours, then offer them food and count how many seeds are stored in their pouches in the next hour. You let your rats rest for one week, and repeat the experiment with the same rats, but offer them unlimited food for the 24 hours prior to the experiment. Run the appropriate statistical test.

A recent study sought to determine if exercising after studying for an exam may help retain information. The 150 student volunteers that participated in the study were randomly assigned to three groups. All students were given a picture memory task that they studied for 15 minutes. After studying, one of the groups was instructed to exercise for 30 minutes immediately after studying. A second group was instructed to wait 1 hour after studying and then exercise for 30 minutes. The third group was instructed to not exercise after studying. The next day all 150 student volunteers were given a test to determine how well they could remember what they studied. Here are the results: The researchers want to test: H0: There is no difference in the distribution of performance on the test for the three treatment groups among the population of all student volunteers like these. Ha: There is a difference in the distribution of performance on the test for the three treatment groups among the…
A group of Industrial Organizational psychologists wanted to test if giving a motivational speech at the end of a meeting would encourage office workers to have a higher output to their work based on the numbers of sales each workers made. The group tested 10 participants that were in two conditions where one meeting ended in a motivational speech and another were no motivational speech was given. Here are the number of sales that was produced by the 10 participants for both conditions: Yes speech: 2, 6, 1, 9, 3, 12, 8, 0, 5, 1No speech: 3, 0, 5, 10, 1, 8, 2, 1, 9, 11Use the four steps of hypothesis testing to find out if there is a significant difference between the two groups, using APA format to answer the question.

question(13): The researcher decided to conduct the study again and recruited an additional 10 children from the full time kindergarden and an additional from the part time kindergarden, This time they matched the children in full time kindergarden and partime kindergarden on SES, gender, age, and vocabulary score .They based their hypotheses on the finding from a previous study and wanted to see if full time kinder garden would have better short term memory recall compared to children who attended partime kindergarden. Researchers read a list of 20 words ,then waited 2 minrderdenutes while the kids were having a snack, then they were asked to tell them how many words they remember. .Those who remember a word got a score of 1. A summary of the results is given below fulltime kindergarden: 15 9 10 8 11 7 14 12 11 13 partime kindergarden : 10 7 9 8 12 6 8 10 7 9 test the hypotheses…
