To assess the effectiveness of a cola video ad for cola B, a random sample of 35 individuals from a target audience was selected to participate in a copy test.Participants viewed two ads, one of which was the ad being tested (cola B). Participants then answered a series of questions about how much they liked the ads. Anadindex measure was created and shown in the accompanying table; the higher the adindex value, the more likeable the ad. State your findings and conclusions.Assume α = 0.05.Click the icon to view the data table of the adindex ratings.Compute the descriptive statistics. Find the mean of the adindex ratings for cola A.(Round to two decimal places as needed.)Find the mean of the adindex ratings for cola B.Mean after workshops = (Round to two decimal places as needed.)Find the mean of the difference of the adindex ratings for cola A and cola B. (Assume the difference to be the cola A data value minus the cola B data value)Mean of the difference = (Round to two decimal places as needed.)Find the variance of the cola A adindex ratings.

A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean exam score on the previous three tests. She then asked them to rate how likely they were to cheat on an exam if the opportunity presented itself with a very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat. Before opening the data, what would you hypothesize about this research question? Open the data set. Before running any statistical analyses, glance through the data. Do you think that your hypothesis will be supported? Conduct descriptive analyses and report them here. Conduct a one-way ANOVA.

A college professor conducted student evaluations at the end of a semester. One important question asked was, "Would you recommend this professor to a friend?” Fifty-four students responded using the following 1-to-5 rating scale. 1 = "absolutely not" 2 = "probably not” 3 = "no opinion" 4 = "probably yes" 5 = "absolutely yes" Student responses were recorded. "Blank" indicates that a student skipped this question on the evaluation. 4 #28: #1: Blank #10: #2: Blank #3: #4: Blank #5: #6: #7: #8: 4 #9: 5 4 5 2 # 11: #12: #13: #14: #15: # 16: #17: 3 Blank 5 Blank Blank 1 5 Blank # 19: #20: #21: #22: #23: #24: #25: #26: 4 #18: Blank #27: 1 2 #30: 1 #31: 3 Blank 5 #29: 5 Blank #32: #33: #34: #35: 1 #37: 5 Blank 4 1 5 4 5 #38: #39: #40: # 41: #42: #43: #44: #36: Blank #45: 2 #46: Blank 1 5 4 Blank #49: 5 #47: Blank #48: #50: #51: #52: Blank #53: 1 5 4 5 5 1 5 1 #54: Blank
In marketing children’s products, it is extremely important to produce television commercials that hold the attention of the children who view them. A psychologist hired by a marketing research firm wants to determine whether differences in attention span exist among advertisements for different types of products. A number of children under 10 years of age are asked to watch one 60-second commercial for one of three types of products, and their attention spans are measured in seconds. The results are shown in the accompanying table: Type of Product Advertised Toys/Games Food/Candy Children’s Clothing 42 55 30 45 58 35 48 52 42 40 60 32 50 57 38 b). What type of error is possible and describe this error in terms of the problem.
While traveling through South America, a student decides to analyze which country is the friendliest. He measures friendliness by seeing whether or not a person, when asked for directions, gives a reply. For each country, he gathers data on hundreds of people. The four countries analyzed are Argentina, Chile, Brazil, and Uruguay.
A randomly sampled group of patients at a major U.S. regional hospital became part of a nutrition study on dietary habits. Part of the study consisted of a 50-question survey asking about types of foods consumed. Each question was scored on a scale from one (most unhealthy behavior) to five (most healthy behavior). The answers were summed and averaged. The population of interest is the patients at the regional hospital. A prior survey of patients had found the mean score for the population of patients to be μ=2.9 After careful review of these data, the hospital nutritionist decided that patients could benefit from nutrition education. The current survey was implemented after patients were subjected to this education, and it produced the following sample statistics for the 15 patients sampled: x¯=3.5 and s=1.2 We would like to know if the education improved nutrition behavior. We test the hypotheses H0:μ=2.9 versus Ha:μ>2.9. The tt test to be used has the test statistic: Answer:
The Condé Nast Traveler Gold List for 2012 provided ratings for the top 20 small cruise ships.† The data shown below are the scores each ship received based upon the results from Condé Nast Traveler's Annual Readers' Choice Survey. Each score represents the percentage of respondents who rated a ship as excellent or very good on several criteria, including Itineraries/Schedule, Shore Excursions, and Food/Dining. An overall score was also reported and used to rank the ships. The highest ranked ship, the Seabourn Odyssey, has an overall score of 94.4, the highest component of which is 97.8 for Food/Dining.

The Computer Anxiety Rating Scale (CARS) measures an individual’s level of computer anxiety, on a scale from 20 (no anxiety) to 100 (highest level of anxiety). Researchers at a large university administered CARS to 80 business students. One of the objectives of the study was to determine whether there is a difference between the level of computer anxiety experienced by female students and male students. Of the 80 student survey takers, 40 were male, 40 were female. The results are in the table below for statistical analysis of variability between the two samples. All of these analyses are run with a 95% level of confidence. Males Females Sample Mean 40.26 36.85 Sample Standard Deviation 13.35 9.42 Perform the test chosen in part (d) of the previous problem and supply this information: a. What is the value of the test statistic? b. Find the probability of getting these results if there is no difference in anxiety ratings between the…
Jocelyn believes that the amount of sleep she tends to get on weekends differs from the amount of sleep she tends to get during the school week. To investigate this claim, she randomly selects 10 weekend days and 10 school days. She consults her smart watch to determine the number of hours she slept for each of the selected days. Here are the data. School week: 7, 7.5, 8, 6.5, 8, 7.5, 7, 6.5, 7, 8Weekend: 9.5, 9.5, 8.25, 8.5, 7.5, 10.25, 8, 7, 9.5, 10 Jocelyn would like to determine if these data provide convincing evidence that the true mean amount of sleep she gets on the weekend differs from the true mean amount of sleep she gets during the school week. She tests H0: μS – μW = 0, Ha: μS – μW ≠ 0, where μW = the true mean amount of sleep Jocelyn gets on the weekend and μS = the true mean amount of sleep she gets during the school week. The conditions for inference are met. What are the values of the test statistic and P-value for a t-test about a difference in means? Find the…
