Find the probability and interpret the results. If convenient, use technology to find the probability The population mean annual salary for environmental compliance specialists is about $60, 500 . A random sample of 45 specialists is drawn from this population. What is the probability that the mean salary of the sample is less than $57,500? Assume σ = $5,000. The probability that the mean salary of the sample is less than $57 500 is (Round to four decimal places as needed )

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
