You work in marketing for a company that produces work boots. Quality control has sent you a memo detailing the length of time before the boots wear out under heavy use.They found that the average length of time until the boots wear out is normally distributed with a mean of 208 days and a standard deviation of 14 days.You would like to run a marketing campaign stating that the boots will last more than 8 months (240 days).

What is the probability that this marketing claim is true (e.g., what is the probability that the length of time until the boots wear out is more than 240 days)?
