Identify a major problem with the study. In a survey conducted by USA​ Today, 1465 Internet users chose to respond to this question posted on the USA Today electronic​ edition: “Is news online as satisfying as print and TV​ news?” 52% of the respondents said​ “yes.”

Listed below are amounts​ (in millions of​ dollars) collected from parking meters by a security service company and other companies during similar time periods. Do the limited data listed here show evidence of stealing by the security service​ company’s employees? Security Service Company: 1.4   1.7   1.6   1.5   1.5   1.6   1.7   1.5   1.5   1.8     Other Companies: 1.7 1.9 1.6 1.8 1.7 1.8 1.6 1.7 1.8 1.7 Find the coefficient of variation for each of the two​ samples, then compare the variation. The coefficient of variation for the amount collected by the security service company is [ans1]%.  (Round to one decimal place as​ needed.) The coefficient of variation for the amount collected by the other companies is [ans2]%.  (Round to one decimal place as​ needed.) Do the limited data listed here show evidence of stealing by the security service​ company’s employees? Consider a difference of greater than​ 1% to be significant. Fill in your choice here [ans3] A. Yes. There is a significant difference in the variation. B. No. There is a not significant difference in the variation. C. Yes. There is a not significant difference in the variation. D. No. There is a significant difference in the variation.
