The lifespan of a laptop battery is normally distributed. If the mean lifespan of a battery is 4 years with a standard deviation of 1.6 years, what is the probability that the next laptop battery you purchase will last between 3.5 and 5.5 years?
CI = (71.98%, 79.45%)
CI = (72.02%, 78.38%)
CI = (70.23%, 80.17%)
CI = (71.41%, 78.99%)
