Use statistical software to find the mean and the standard deviation for the Buena buses.Does the Buena data seem to be in line with that reported by the manufacturer? Specifically,what is the probability of the sample mean being less than Buena’s, given the manufacturer’s data? (Round mean, standard deviation and z value to 2 decimal places and final answer for probability to 4 decimal places.)
