max2010maxim [7]

The probability that the sample mean would differ from the population mean by less than 655 miles in a sample of 79 tires if the manager is correct is = 0.9805.

<h3>

What is the calculation for the above?</h3>

P (\bar{x} < 655) ≡ P [ |( \bar{x} - μ)/√(σ²/n) | <655/√(6,220,036/ 79)]

= P (| Z | < 3.55)

= P - 3.55 < Z < 3.55) Using the z -score table

= 0.9998 - 0.0193

= 0.9805
