A professor has a class with four recitation sections. Each section has 7 students (rare, but there areexactly the same number in each class...how convenient for our purposes, yes?). At first glance, theprofessor has no reason to assume that these exam scores from the first test would not beindependent and normally distributed with equal variance. However, the question is whether or notthe section choice (different TAS and different days of the week) has any relationship with howstudents performed on the test.Group-1Group-2 Group-3 Group-476.960.575.570.778.171.378,7102.271.454.580.167.372.656.182.889.574.171.868.172.968.968.181.770.567.662.268.892.1First, run an ANOVA with this data and fill in the summary table.

A professor wants to know whether or not there is a difference in comprehension of a lab assignment among students depending on if the instructions are given all in text, or if they are given primarily with visual illustrations. She randomly divides her class into two groups of 15, gives one group instructions in text and the second group instructions with visual illustrations. The following data summarizes the scores the students received on a test given after the lab. Let the populations be normally distributed with a population standard deviation of 5.32 points for both the text and visual illustrations.

1. According to a fast food manager, the average number of customers between 8am to 11am is 10, with a variance of two. His friend from other outlet does not believe that the variance is two. He counts the number of customers in 15 other outlets and obtained the following data: Table 1 Number of Outlet Customers 1 11 2 10 3 9 4 10 10 6 11 7 11 10 12 10 11 7 12 13 11 14 10 15 11 Based on the data, help the manager to decide whether the variance is different from two using a = 0.05.
Each of the boxplots shown summarizes 24 student scores on a recent test in two different classes. The boxplots are drawn using a common numerical scale. Which of the following must be true? 1. The lower 25% of Class B are much more spread out than the lower 25% of Class A 2. More people scored below the lower quartile for Class A than Class B 3. The distribution for Class B is skewed left and has a noticeable outlier as well, while the distribution for Class A is somewhat skewed right 4.Class A had more people between the median and the lower quartile than Class B. 3.The distribution for Class A is somewhat symmetric, while the distribution for Class B is skewed right with a noticeable outlier as well

The top 5 students of grade 10 section Oxygen class, James, Jessie, Jane, John, and Jack, are so eager to know their respective ranks. They keep on asking their teacher, Mr. Jacob, about who got the first rank, second, and so on. Mr. Jacob challenged them and said, "For all of you, in relation to all Grade 10 student's grades, you got the 90th percentile, 9th decile, 3rd quartile, 95th percentile, and 8th decile, respectively. Now tell me the correct rankings and prove to me that you are worth the rank you are in." Which of the following is the most probable ranking of the five students?

Use the following scenario to answer the next 6 questions: M&Ms are your favorite vending machine snack and you purchase them often. Lately, it seems like the bags have been having a disproportionate distribution of the colors. The company claims that 24% of the candies per bag should be blue. You decide to test this claim for yourself. You purchase a large bag and find that 38 of the 224 candies are blue. Before complaining to the company, you want to be fairly sure of your accusation, so you set a 1% significance level for your test. Do you have sufficient evidence that the color distribution is different than advertised? In this scenario, the decision to use a two-tailed versus a one-tailed test affected our ability to reject the null (and thus our conclusion). Group of answer choices True False

A person tested the hypothesis Ha #26 versus As6 and scribbled down his calculations. When his friend came along and quickly wanted copy his work, he did not read properly and wrote down the following 1. The sample mean is equal to 4. 2. The sample variance is equal to 1 3 The rejection region is < tnon 10=-1.833. 4 The test statistic is 3.0. 5 The conclusion is to reject H because the test statistic I-30<-L833 Which ONE of the above statements is CORRECT
