QUESTION 10 The average hourly wage at Neco Inc. is $14.6 and the corresponding variance to be $77. What is the coefficient of variation? QUESTION 11 The weights (in pounds) of a sample of 36 individuals were recorded and the following statistics were calculated mean = 160 range = 60 mode = 165 variance = 324 median = 170 The coefficient of variation equals O 0.20312% O 0.1125% 203.12% 11.25%Events A and B are Independent. If P(A) = 30% and P(B) = 49.7%, then P(B | A) = (Hint: Put Answer = 0 if it is not possible to calculate because not enough information is provided) QUESTION 16 If A and B are Independent events with P(A) = 37.7% and P(B) = 30.4%, then P(A UB) = (Hint: Put Answer = 0 if it is not possible to calculate because not enough information is provided) QUESTION 17 If A and B are Independent events with P(A) = 21.9% and P(B) = 36.3%, then P(An B) = (Hint: Put Answer = 0 if it is not possible to calculate because not enough information is provided)QUESTION 5 P(A) = 28.6% and P(B)=45.9%. Also given is P(A U B) = 49.2%. A and B are neither mutually Exclusive nor Independent Events, then P(An B) = (Hint: Put Answer = 0 if it is not possible to calculate because not enough information is provided) QUESTION 6 A and B are mutually exclusive, but not collectively exhaustive. If P(A) = 0.23 and P(B) = 0.44 then P(A and B) = QUESTION 7 If P(A) - 40.53%, P(B) = 40.53%, and P(An B) = 15.97%; then P(A u B) =QUESTION 18 There is a probability of 15% that a KBC contestant will win a decent amount of money on the show.
