Please write clear.
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: 1.5 1.6 1.7 1.3 1.6 1.3 1.5 1.8 1.4 1.6 Other Companies: 18 1.9 16 1.8 18 1516 17 16 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 | (Round to one decimal place as needed.)Explanation / Answer
solution:-
1. the coefficient of variance for the amount collected by the security service company is
standard deviation (s)= 0.1636
mean (x) = 1.53
coefficient of variation = ( s / x ) * 100%
= (0.1636 / 1.53)*100
= 10.7 %
2. the coefficient of variation for the amount collected by the other companies is
standard deviation (s) = 0.1247
mean (x) = 1.7
coefficient of variation = ( s / x ) * 100%
= (0.1247 / 1.7)*100
= 7.3 %
