Suppose that a population of measurements is normally distributed with mean μ and standard deviation σ. (Round your z value to 2 decimal places and the remaining answers to 3 decimal places.)

Write an expression (involving μ and σ) for a tolerance interval containing 98 percent of all the population measurements.
