Help please! (b) Despite the results being statistically significant, the authors stated in their article about the first study: "The field study did not support an examination of why more creative store windows led consumers to enter the stores. … The use of actual retailers' real store windows meant that the level of creativity was not the only variable that differed among the retailers and their windows." How does the second study address some of those drawbacks? Does either study suffer from a lack of realism? Choose the best explanation. A) The drawbacks in the first study were that it was an observational study and that it did not control for confounding variables (such as variations in merchandise and potential customers). The second study addresses these drawbacks by using the same retailer and the same merchandise, and by only changing the creativity of the window display. Neither study suffers from a lack of realism, since statistically significant results were…

Scenario: A researcher wants to see whether ESP abilities in psychics differ based on environment. Thus, the researcher has psychics predict card suits in both a fortune-telling environment (e.g., low lighting, candles, a crystal ball), and in a standard lab environment. They complete 100 trials of the task in each environment, with the environment type counterbalanced between participants. All 30 psychics completed the card prediction task in both environments. Accuracy rates are compared. Question: What is the most appropriate statistical test to conduct given this scenario? Independent samples t-test Correlated groups t-test Pearson's r correlation Phi correlation

RDB Company produced four types of tires recently, Tires A, B, C, and D. Before this year ends, RDB would like to identify which type of tire will give the least amount of tire wear after 30,000 miles. The response variable is the difference in maximum tread thickness on a tire between the time it is mounted on the wheel of the car and after it has completed 30,000 miles. Four types of tires will be used to get an estimate of experiment error. In order to conduct this study, four cars, a BMW, a Ferrari, a Lamborghini, and a Mercedes Benz were selected to accommodate the 16 tires. The results for this design are given in the following table. Which tires of cars are significantly different? Use tukeys with hsd for your post hoc test.
