Suppose that the walking step lengths of adult males are normally distributed with a mean of 2.6 feet and a standard deviation of 0.3 feet. A sampleof 59 men's step lengths is taken.Step 1 of 2: Find the probability that an individual man's step length is less than 2.3 feet. Round your answer to 4 decimal places, if necessary.

The normal distribution in the center are generally denser and basically less denser at tails.…

Answered: Suppose that the walking step lengths…
