A survey shows that people use cell phones an average of 1.6 years with a standard deviation of 0.3 years. A user is randomly selected. If cell phone use is normally distributed, we can use Excel to calculate the probability that the randomly selected user uses their phone for less than 1 year with the function: (a) =1 - NORM.DIST(1, 1.6, 0.3, TRUE) (b) =1 - NORM.INV(1, 1.6, 0.3) (c) =NORM.INV(1, 1.6, 0.3) (d) =NORM.DIST(1, 1.6, 0.3, TRUE) (e) =1 - NORM.DIST(1, 1.6, 0.3, FALSE)
