11. A manufacturer of electronic components is in- terested in determining the lifetime of a
certain type of battery. A sample, in hours of life, is as follows:
123, 116, 122, 110, 175, 126, 125, 111, 118, 117. (a) Find the sample mean and median.
(b) What feature in this data set is responsible for the substantial difference between the
two?
mean= 120.3 and median 125, 176 is an extreme observation
mean= 124.3 and median 120, 175 is an extreme observation
mean= 129.3 and median 125, 176 is an extreme observation
mean= 120.3 and median 125, 175 is an extreme observation
