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: Other Companies: 1.4 1.7 1.5 1.3 1.4 1.5 1.7 1.6 1.4 1.6 O 1.6 1.9 1.5 1.8 1.7 1.9 1.5 1.6 1.7 1.6 Find the coefficient of variation for each of the two samples, then compare the variation. The coefficient variation for the amount collected by the security service company is 9.1 %. (Round to one decimal place as needed.) The coefficient of variation for the amount collected by the other companies is 8.8 %. (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. O A. Yes. There is a significant difference in the variation. O B. Yes. There is not a significant difference in the variation. OC. No. There is a significant difference in the variation. O D. No. There is a not significant difference in the variation.
