Fourteen people answered that they generally sell two cars; nineteen generally sell three cars; twelve generally sell four cars; nine generally sell five cars; eleven generally sell six cars. Calculate the following. (Round your answer to two decimal places.)
sample mean = x
Answer)
Mean = (sum of all the observations)/(number of observations)
Mean = ((14*2) + (19*3) + (12*4) + (9*5) + (11*6))/(14+19+12+9+11)
Mean = 3.75384615384
Sample mean = 3.75
