I'm getting the steps mixed up in my mind. Can I see an example of how this problem would be completed? Thank you. Please include the steps.

Legal4U magazine surveyed the salaries of lawyers in New York City. They computed a mean annual salary of $162,000 dollars with a random sample of 94 salaries. You can assume a standard deviation of $45,000 and the population is normally distributed.

A) What is the standard deviation of the sampling distribution for this situation? Round to four places and answer using proper notation.

B) Find the probability that a single randomly selected salary has a value between $150,861 and $176,853. Define the random variable used, include notation and quantities.

C) Find the probability that a random sample of size n=94 has a mean value between $150,861 and $176,853. Define the random variable used. Use correct probability notation.
