The survey data is presented in Table 1 below. Ms. Spring is not sure the results of the survey support the position that the accident rate among drivers wearing flip-flops is higher than the accident rate among drivers not wearing flip-flops. She is uneasy with the survey results, fearing that the survey might reveal the worst-case outcome, namely, that drivers who wear flip-flops have lower accident rates than drivers who do not wear flip-flops. In addition, she is unsure how to analyze the data before making a final decision whether or not to use the survey results in settlement negotiations or, if needed, at trial. Ms. Spring needs help in making sense of the data. Does the data

support her position? In addition, Ms. Spring is concerned about the limitations that might exist regarding the methods being used to analyze the data. Are there any recommendations that might overcome the limitations?
