Acompany with a large fleet of cars hopes to keep gasoline costs down and sets a goal of attaining a fleet average of at least 25 miles per gallon. to see if the goal is being met, they check the gasoline usage for 50 company trips chosen at random, finding a mean of 24.49 mpg and a standard deviation of 5.06 mpg. is this strong evidence they have failed to attain their fuel economy goal? complete parts a through e below. a) write appropriate hypotheses.

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b.the means of the data sets are within 3 units from eachother. c.the data sets have the same standard deviation. d.the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.
