A manufacturer knows that their items have a normally distributed lifespan, with a mean of 2.2 years, and standard deviation of 0.5 years.

The 3% of items with the shortest lifespan will last less than how many years?

Give your answer to one decimal place.

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). The mean maximum oxygen uptake for elite athletes has been found to be 67.5 with a standard deviation of 8.1. Assume that the distribution is approximately normal.

Find the probability that an elite athlete has a maximum oxygen uptake of at least 78.84 ml/kg.

Find the probability that an elite athlete has a maximum oxygen uptake of at most 58.59 ml/kg.

Find the probability that an elite athlete has a maximum oxygen uptake of 58.59 ml/kg.
