Select the correct response. For a research study, there are five options for the first question, four options for the second question, and three options for the third question. Using a list, there would be outcomes for the sample space. For a similar study, if there are only four options for the first question, the sample space would have outcomes.
Students in two elementary school classrooms were given two versions of the same test, but with the order of the questions arranged from easier to more difficult in version A and in reverse order in version B. Randomly selected students from each class were given version A and the rest given version B. The results are Version A:n1=31,x¯1=83,s1=4.6Version B:n2=32,x¯2=78,s2=4.3 Use a 0.01 significance level to test the claim that Version A is easier than version B.(Make sure you have the four steps shown similar to the examples that I gave) Assume that the two independent samples have been randomly selected from normally distributed populations. Instruction: 1) Must contains 4 steps as shown on the instructor's video. 2) Must identify whether the null hypothesis or the alternative hypothesis is the claim. 3) When doing the calculation, do not calculate standard error. 4) When finding the p-value, must show whether it is left-, right-, or two-tailed. 5) When drawing conclusion, must…
A teacher has two large containers filled with blue, red, and green beads, and claims the proportion of red beads is the same in each container. The students believe the proportions are different. Each student shakes the first container, selects 50 beads, counts the number of red beads, and returns the beads to the container. The student repeats this process for the second container. One student’s samples contained 10 red beads from the first container and 16 red beads from the second container. Let p1 = the true proportion of red beads in container 1 and p2 = the true proportion of red beads in container 2. Which of the following are the correct hypotheses to test the students’ claim?

Ethan has a bag that contains strawberry chews, apple chews, and lime chews. He performs an experiment. Ethan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Ethan performs the experiment 47 times. The results are shown below: A strawberry chew was selected 36 times. A apple chew was selected 9 times. A lime chew was selected 2 times. If the experiment is repeated 600 more times, about how many times would you expect Ethan to remove a lime chew from the bag? Round your answer to the nearest whole number.
An experiment investigated the effect of length and repetition of TV ads on students choosing to eat at Del Taco. All 60 students watched a 40-minute television program that included ads for Del Taco. Some students saw a 30-second commerical; others a 90-second commerical. The same commerical was shown either 1, 3, or 5 times during the program. After the viewing, each student was asked to rate their craving for Del Taco on a scale of 0 to 10. What is the response variable?A. 1, 3, or 5 commercials during the 40-minute television programB. craving for Del Taco on a scale of 0 to 10C. 60 studentsD. 30-second and 90-second commericialsE. 40-minute television program
Ida wants to know if people prefer for one brand of chocolate chip cookie dough over another. To test this, she bakes eight dozen cookies from dough made by each of 4 manufacturers and labels the brands A, B, C, and D, to conceal the name of the company from the tasters. She then selects a random sample of 96 students at her school to try each brand of cookie and choose the brand they like best. The cookies are tasted in random order. Here are the results: Cookie Brand Number of choosing brand A 26 18 24 28 Ida performs the appropriate y procedure to test the hypothesis that the brands are preferred equally. What brand category that contributes the most to the value of the ? statistic? OD O A O BA O All four components are roughly equal. NEW FOR YOU: 40% OFF
At an assembly plant, workers assemble parts for a piece of farm equipment. The supervisor conducted an experiment to compare the effectiveness of three assembly methods, A, B, and C. Eighteen employees were randomly assigned, six employees each, to one of the three methods. After completing their training, each person was asked to assemble five pieces of equipment using his or her training method. The average time to complete the assembly of all five pieces of equipment was recorded. (a) What type of study design is used? O independent groups design O repeated measures design O matched pairs design O randomized block design What are the experimental units in this study? O the 18 employees O the five pieces of equipment to be assembled O the three assembly methods O the average time to assemble five pieces of equipment (b) What are the treatments? O the 18 employees O the five pieces of equipment to be assembled O the three assembly methods the average time to assemble five pieces of…

A report described teens' attitudes about traditional media, such as TV, movies, and newspapers. In a representative sample of American teenage girls, 42% said newspapers were boring. In a representative sample of American teenage boys, 45% said newspapers were boring. Sample sizes were not given in the report. A button hyperlink to the SALT program that reads: Use SALT. (a) Suppose that the percentages reported had been based on a sample of 50 girls and 40 boys. Is there convincing evidence that the proportion of those who think that newspapers are boring is different for teenage girls and boys? Carry out a hypothesis test using ? = 0.05. (Use pgirls − pboys.) Find the test statistic. (Round your answer to two decimal places.) z = Find the P-value. (Round your answer to four decimal places.) P-value = State your conclusion. Reject H0. We do not have convincing evidence that the proportion of girls who say that newspapers are boring is different from the proportion of boys who…
