1) What is the standard deviation of the sampling distribution for this situation? Round to four places. Show work and answer using proper notation. 2) Find the probability that a single randomly selected salary has a value between $134,999 and $141,740. Your write up should include all of the following: o Define the random variable you are using. o Use correct notation to label all quantities. o State or show how you found your final probability. You can use tables or StatCrunch, just specify what you did. o Show your answer using full and correct probability notation. Round to four places. o State your final result in a complete-sentence form, with correct context, numbers and units. 3) Find the probability that a random sample of size n = 72 has a mean value between $134,999 and $141,740.
