- BREAKFAST AND TEST SCORES 1 of 4 What type of test should this researcher use? Conventional wisdom says that eating a healthy breakfast can improve your health and your weight, but can it also affect your test scores? In order to test this, a school program convinces a group of students to skip breakfast one morning before taking a Basic English test. Eighteen students received breakfast before taking the test, and twenty-one students did not eat breakfast and recorded their performance on the English test. What type of research test should this researcher use? Their results are as follows:Compare What-If Analysis using Trial and Error and Goal Seek to the given scenario: Let's say a student is enrolled in an online class at a learning institution for a semester. His overall average grade stands at 43% in the course (Term Grade is 45%, Midterm Grade is 65%, Class Participation is 62% and Final Exam is 0%). Unfortunately, he missed his Final Exam and was given 0%. However, he has the opportunity to redo his Final Exam and needs at least an overall average of 60% to pass the course. How can you use Trial and Error and Goal Seek to find out what is the lowest grade he needs on the Final Exam to pass the class? Which method worked best for you and why?You have conducted a series of experiments to reduce the proportion of scrapped battery cells to 1% in your manufacturing plant. What is the probabilty of testing 51 cells without finding a defect until the last cell?
- What the answer to this questionThere exists 2 treatments for a specific illness. One uses pills, and the other infrared pulses. To measure the illness, you measure the level of the a particular marker in the blood; the higher the marker, the worse the disease. Which of the following tests the claim that the infrared pulse treatment improves outcomes better ?Attached
- A personal trainer wanted to test the effectiveness of two different workout routines. She took a random sample of 70 of her clients and, in a random order, had them complete one of the two routines for two weeks. Then, after a one-month waiting period, she asked them to come back and do the other routine for two weeks. After each two-week period of the exercise routines, she measured their performance on a physical fitness aptitude test. She found the average difference in aptitude scores between the two routines for each client was 30.4 with a standard error of 3.2. What would be her 85% confidence interval for the average difference in the effectiveness of the two routines? (3 decimal places) ( , )An aerosolized vaccine for measles was developed in Mexico and has been used on 44 million children since 1980. Aerosolized vaccines have the advantages of being able to be administered by people without clinical training and do not cause injection‐associated infections. The percentage of children developing an immune response to measles after receiving the subcutaneous injection of the vaccine is 95%,95%, and for those receiving the aerosolized vaccine, it is 85%85% . There are 2020 children to be vaccinated for measles using the aerosolized vaccine in a small rural village in India. We are going to count the number who developed an immune response to measles after the vaccination. (b) What is the probability that at least one child does not develop an immune response to measles after receiving the aerosolized vaccine? (Enter your answer as a proportion rounded to four decimal places.)You are working on a magic pill that you think might totally eliminate pain when given to patients who are experiencing severe pain. In your work, you have discovered three ingredients that might be effective if each is used alone. Which drug therapy works best? The dependent measure is the degree of pain relief after 30 minutes of ingestion. A higher value means greater pain relief. Drug 1: 5,7,11,10,10,6,4,8 Drug 2: 13,12,12,8,7,8,12,11 Drug 3: 15,11,13,10,10,16,14,11 Placebo: 10,8,5,9,6,13,11,16 Set up your hypotheses, Report your Hypotheses in narrative and symbolic form. Use a = .01 What is the Dependent Variable? What is the Independent Variable? How many levels exist for the independent variable? Perform the appropriate ANOVA. Present your results in an ANOVA Summary Table Complete the Scheffe' Test if you find a Significant F . Compute the R2 If necessary
- Spam: A researcher reported that 71.8% of all email sent in a recent month was spam. A system manager at a large corporation believes that the percentage at his company may be 70%. He examines a random sample of 500 emails received at an email server, and finds that 374 of the messages are spam. Can you conclude that the percentage of emails that are spam is greater than 70% ? Use both a=0.10 and a=0.01 levels of significance and the P-value method with the TI-84 Plus calculator. Part: 0/ 4 Part 1 of 4 State the appropriate null and alterņate hypotheses. do OPlease provide solution asap for each and select correct option please ASAP for eachPlease help needed on this asap. Thanks so much! It has been observed that some persons who suffer colitis, again suffer colitis within one year of the first episode. This is due, in part, to damage from the first episode. The performance of a new drug designed to prevent a second episode is to be tested for its effectiveness in preventing a second episode. In order to do this two groups of people suffering a first episode are selected. There are 170 people in the first group and this group will be administered the new drug. There are 132 people in the second group and this group wil be administered a placebo. After one year, 14% of the first group has a second episode and 18% of the second group has a second episode. What is a 90% confidence interval for the difference in true proportion of the two groups.
