How charge-life exceeding hundred minutes would be unusual

Reference no: EM13140588

The charge-life for a certain lithium ion battery is normally distributed with mean 90 minutes and standard deviation 35 minutes. What is the probability that a single randomly sampled battery of this type lasts longer than 100 minutes. Does this suggest that a charge-life exceeding 100 minutes would be unusual?
