An instructor teaches three introductory Medicine sections covering the same material. He has made up a different final exam for each section. Still, he suspects that one of the versions is more difficult than the other two. he decides to experiment to evaluate the difficulty of the exams. He randomly selects five volunteers for each class during the review period just before finals. Class 1 volunteers are given version 1 of the exams, Class 2 volunteers get version 2, and Class 3 volunteers receive version 3. Of course, all volunteers are sworn not to reveal any of the exam questions, and also, all of the volunteers will receive a different final exam from the one they took in the experiment. The following are the results. Does this study suffice the assumptions in employing One-way ANOVA in interpreting the results? Explain why or why not?
The percentage of people in the population suffering from a certain disease is 32%. There is a test to detect the disease that is quite accurate. Of the people who have the disease and who undergo the test, it is indicated that 2% of them do not have the disease. Of the people who do not have the disease and who undergo the test, 2% of them are reported to have the disease. Suppose a person takes the test and indicates that they have the disease. Find the probability that the person does have the disease. Round your answer to two decimal places.
A high school principal decides to conduct a study in which she examines two chemistry classes in her high school. Her goal is to explore the effectiveness of two different instructional techniques she has become acquainted with and she will determine effectiveness through course grades. One class is taught by Ms. Howes, who will be using an instructional technique called "Chemistry Applications." The other class is taught by Ms. Moore, who will be using an instructional technique called "Chemistry In the Real World." What type of study is the principal planning on conducting? Question 19 options: A) A correlational study B) A quasi-experimental study C) A descriptive study D) A mixed-methods study
A law firm is evaluating the delivery time of two courier delivery services in Cape Town. They believe that there is a difference between the average delivery times for the two courier services. To investigate this matter further, the firm decides to use both courier services daily over a two month period for deliveries to similar destinations. The delivery times for each courier service are recorded over the two month period. It is found that Courier 1 was used by the firm 12 times and their average delivery time was 43 minutes with of standard deviation of 12 minutes. Courier 2 was used 15 times, and their average delivery time was 36 minutes with a standard deviation of 8 minutes. Construct a 95% confidence interval for the difference in the true mean delivery times for Courier 1 and Courier 2 (rounded off to two decimals).
A researcher wondered whether there was a relationship between age group (adolescents, young adults and adults) and views about the future (positive views, neutral views or negative views). Participants from each age group answered a questionnaire testing their views about the future and based on their score they were categorized as having either positive views, neutral views or negative views. Out of 1000 participants, 250 were adolescents, 450 were young adults and 300 were adults; Of all the participants, 200 had positive views, 500 had neutral views and 300 had negative views.a. Complete the expected frequencies in the following table. Adolescents Young adults AdultsPositive viewsNeutral views Negative views

If you set up your study as a block design, the usual convention is to have 1 experimental unit per treatment per block. So if there is 2 treatments there would be 2 experimental units per block? True or False
Vaccine A and B are given to 20% and 50% of the individuals in Country X, respectively, to protect them from becoming infected with Covid-19. The remaining persons have not received any vaccinations against Covid-19. None of them received more than one vaccination. The rates of Covid-19 infection for people vaccinated with Vaccine A, people vaccinated with Vaccine B, and unprotected people are known to be 20%, 10%, and 50%, respectively. What is the likelihood of a person being unvaccinated if they are randomly chosen and discovered to be infected with Covid-19?
A group of 250 people, if it is known that their average weekly wage is 324.48 dinars. Of them, 7 were earning 12.2 dinars an hour, 21 of them earned 544.32 dinars a week, 58 of them earned 48.96 dinars a day, 9 of them earned 6.19 dinars an hour, and 18 of them earned 74.48 dinars a day. . Knowing that they work 7 hours a day, and 6 days a week, find the following 1- The average wage for the rest of the people in the week ۲- The average wage for the remaining people per hour
A huge pencil bag contains 40 pencils of two different shades, 4B and 6B. Initially, there are x numbers of 6B pencils in the bag. If 45 more 6B pencils are put in the bag, the probability of randomly picking a 6B pencil now will be quadruple that of the previous probability of picking a 6B pencil. With the given information, evaluate the original number of 6B shade in the pencil bag.
An instructor has awarded 20% of the course grade to assigments, 10%to activities, 15% to exam-1, 15% to exam-2, 15% to exam-3 and 25%to the final exam. If a student scores 110 points from a total of 120total assignment points, 70 from a total of 90 activity points, 92% onexam-1, 88% on exam-2, 91% on exam-3 and expects to score 85% onthe final. What will be the student’s percentage score in the course onwhich the grade will be based?
A motion picture industry analyst is studying movies based on epic novels. The following data were obtained for 10 Hollywood movies made in the past five years. Each movie was based on an epic novel. For these data, x1 = first-year box office receipts of the movie, x2 = total production costs of the movie, x3 = total promotional costs of the movie, and x4 = total book sales prior to movie release. All units are in millions of dollars. x1 x2 x3 x4 85.1 8.5 5.1 4.7 106.3 12.9 5.8 8.8 50.2 5.2 2.1 15.1 130.6 10.7 8.4 12.2 54.8 3.1 2.9 10.6 30.3 3.5 1.2 3.5 79.4 9.2 3.7 9.7 91.0 9.0 7.6 5.9 135.4 15.1 7.7 20.8 89.3 10.2 4.5 7.9 a) If x2 (production costs) and x4 (book sales) were held fixed but x3 (promotional costs) were increased by 1.1 million dollars, what would you expect for the corresponding change in x1 (box office receipts)? (Use 2 decimal places.)b) Test each coefficient in the regression equation to determine if it is zero or not zero. Use level of…
