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 1.5 1.6 1.4 1.5 1.7 1.4 1.3 1.6 Other Companies: 1.8 1.9 1.5 1.7 1.6 1.9 1.6 1.5 1.9 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 nothing%. (Round to one decimal place as needed.) The coefficient of variation for the amount collected by the other companies is nothing%. (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. A. Yes. There is not a significant difference in the variation. B. No. There is a significant difference in the variation. C. No. There is a not significant difference in the variation. D. Yes. There is a significant difference in the variation.

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
