You want to construct a 90% confidence interval for the population mean height of all adults in Rexburg. Assume the population is normally distributed with a population standard deviation of 20 inches. If you want a margin of error of 2 inches, how many people should you include in your study?

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
