A study conducted by researchers was designed "to determine if application of duct tape is as effective as cryotherapy in the treatment of common warts." The researchers randomly divided 54 patients into two groups. The 27 patients in group 1 had their warts treated by applying duct tape. The 27 patients in group 2 had their warts treated by cryotherapy. Once the treatments were complete, it was determined that 67% of the patients in group 1 and 85% of the patients in group 2 had complete resolution of their warts. The researchers concluded that cryotherapy is significantly more effective in treating warts than duct tape. Complete parts (a) through (d) below. (a) What is the research objective? O A. To determine if duct tape is as effective as cryotherapy in the treatment of warts O B. To determine if duct tape is effective in the treatment of warts O C.

There are 54 patients with warts. O D. 67% of patients in group 1 and 85% of patients in group 2 had resolution of their warts. (d) What is the conclusion of the study? O A.

He has a market researcher survey the first 90 customers who come into the food court during weekend mornings to determine what types of food the shoppers would like to see added to the food court. Complete parts (a) and (b) below. (a) The survey has bias. Determine whether the flaw is due to the sampling method or the survey itself. For biased surveys, identify the cause of the error. What is the cause of the bias? O A. Sampling bias O B. Response bias O C. Nonresponse (b) Suggest a remedy to the problem. Which of the following is the best way to remedy this problem? O A. Reword the question so that it is balanced. B. Increase the sample size so that more people respond to the question. O C. Ask customers throughout the day on both weekdays and weekends. Time Remaining: 01:29:14 Next3 A web page design firm has two designs for an online hardware store. To determine which is the more effective design, the firm uses one page from 1:00PM until 6:00PM and a second page from 6:00PM until 11:00PM. For each visit, the firm records the amount of time visiting the site and the amount spent by the visitor. Complete parts (a) through (c) below. (a) What is the explanatory variable in this study? Is it qualitative or quantitative? O A. The explanatory variable is the time of day. This explanatory variable is qualitative. O B. The explanatory variable is the amount spent by the visitor. This explanatory variable is quantitative. O C. The explanatory variable is the amount of time visiting the site. This explanatory variable is quantitative. O D. The explanatory variable is the web page design. The explanatory variable is qualitative (b) What are the two response variables? For each response variable, state whether it is qualitative or quantitative. Select all that apply. A. One response variable is the web page design. This response variable is qualitative. B. One response variable is the amount of time visiting the site. This response variable is quantitative. C. One response variable is the time of day. This response variable is qualitative. D. One response variable is the amount spent by the visitor. This response variable is quantitative. (c) Explain how confounding might be an issue with this study. Choose the correct answer below. O A. Since there are two response variables in this study, they may interact, causing the results to be misleading or incorrect. O B. Since the designs are being tested with two different times of day, preferences depending on the time of day may affect the response variables for those groups. O C. Since there is only one explanatory variable, and two response variables, the explanatory variable will not affect both response variables equally, resulting in misleading results. O D. Since the variables are not all quantitative or all qualitative, they may interact, causing the results to be misleading or incorrect.
