Please DO NOT answer the question, as I just need the right formulas in the form of plugging the numbers from the word problem into it. I struggle with this. And I need to find what the percentage is of the money she makes compared to other babysitters. Please help.
Your babysitter claims that she is underpaid given the current market. Her hourly wage is $12$ per hour. The normal average is $14$ per hour with a standard deviation of $1.9$. Calculate the $Z$ score and use the table to find the standard normal probability. Based on your findings, should you give her a raise? Explain your reasoning as to why or why not.
