Suppose that a Restaurant chain specialized with pasta having three branches in aparticular geographic location would like to evaluate the service at this restaurant.The researcher for the restaurant hires 18 investigators (evaluator) with variedexperiences in food- service evaluations. After the initial consultations, the 15investigators are stratified into five blocks of three-based on food service evaluationexperience- so that three most experience evaluators are placed in block 1, the nextthree most experienced evaluators are placed in block 2, and so on. Within each of thefive homogeneous blocks, the three evaluators are then randomly assigned toevaluate the service at a particular restaurant using a rating scale from 0 (low) to 20(high). The results are summarized in the table.Blocks of Evaluators12345X1819161014RestaurantsY1817161820Z121311109Use a level of significance of a = 0.05, is there evidence of a difference in evaluationbetween restaurants?

5. A psychologist would like to examine the effects of different testing methods on the final performance of college students. One group gets regular quizzes, one group gets three large exams, and the third group only gets a final exam. At the end of the course, the psychologist interviews each student to get a measure of the student's overall knowledge of the material. a. Use a= .05. Conduct the Four Steps for Hypothesis Testing. Then, complete the table below with all the required calculations. b. Are the data sufficient to conclude that thier is a significant difference among the three methods? Write your answer in the form of a sentence. c. Conduct a Tukey's HSD to determine if there is a sigificant difference between any of the 3 groups.

5. Make a conclusion/decision on the problem using hypothesis testing. A group of ten Grade 12 students were given a 45-item pre-test before attending a review. A 45-item post-test was also administered two weeks after the review. Given the following hypothetical data, check if there is significant difference between the pre-test and the post-test result.

1. Select two or three health-related issues that are affected by social, behavioral, or cultural factors (e.g., socioeconomic status, work environment, race, gender, etc.), and discuss how you would approach collecting and analyzing data to make accurate generalizations about the population as a whole. 2. Compare and contrast using hypothesis testing and estimation to analyze the data. 3. Which method is more appropriate for generalizing about the population for the issues you chose?
The data below was collected from Math 13 students. They were asked how many units they were taking this semester and to rate their math anxiety level, on a scale from 0 to 10. For each hypothesis test, provide the claim, critical values, test statistic and conclusion. 1) Test the claim that men and women are taking the same number of units, on average.2) Test the claim that men and women have the same level of math anxiety, on average.3) Test the claim that the proportion of people taking over 12 units is the same for men and women.4) Test the claim that the standard deviation for the number of units taken this semester is the same for men and women.5) Divide the data into two groups: those with 0-5 math anxiety and those with 6-10 math anxiety. Test the claim that the average number of units is the same for these two groups. 0-5 6-10 n = n =x = x=s = s=…
Solve the following problems following the sequential steps of hypothesis testing. 1. In a recent CPA Board Examination, 60 out of 80 students from St. Michaels College of Accountancy and 72 out of 98 students of St. Peters College of Accountancy passed. Are the students of St. Michaels better than the students of St. Peters? Use 5% level of significance. 2. As part of an industrial training program, some trainees are instructed by method 1, which is by teaching machines as well as some personal attention by an instructor, and some are instructed as method 2, which is by straight teaching machine instruction, and the following are the scores they obtained on an appropriate achievement test: Method 1 81 71 79 83 76 75 84 90 83 78 Method 2 69 75 72 69 67 74 70 66 76 72 Compare the effectiveness of the two methods at 5% level of significance.
