A study of the amount of time it takes a mechanic to rebuild the transmission for a 1992 Chevrolet Cavalier shows that the mean is 8.4 hours and the standard deviation is 1.8 hours. If 40 mechanics are randomly selected, find the probability that their mean rebuild time exceeds 8.1 hours
A study of the amount of time it takes a mechanic to rebuild the transmission for a 1992 Chevrolet Cavalier shows that the mean is 8.4 hours and the standard deviation is 1.8 hours. If 40 mechanics are randomly selected, find the probability that their mean rebuild time exceeds 8.1 hours.
A study of the amount of time it takes a mechanic to rebuild the transmission for a 2002 Cavalier shows that the mean is 4.5 hours and the standard deviation is 1.75 hours. If 64 mechanics are randomly selected, find the probability that their mean rebuild time is less than 5.25 hours. (8)
A study of the amount of time it takes a mechanic to rebuild the transmission for a 2005 Chevrolet Cavalier shows that the mean is 8.4 hours and the standard deviation is 1.8 hours. If 40 mechanics are randomly selected, find the probability that their mean rebuild time exceeds 9.1 hours. A. 0.1046 B. 0.0069 C. 0.0046 D. 0.1285
A study of the amount of time it takes a mechanic to rebuild the transmission for a 2010 Chevrolet Colorado shows that the mean is a 4 hours and the standard deviation is 18 hours. It 40 mechanics are randomly selected, find the probability that therm rebuild time is less than 8.9 hours. Round to four decimal places.
