The mean starting salary for nurses is 67,694 dollars nationally. The standard deviation is approximately 10,333 dollars. Assume that the starting salary is normally distributed.

Round the probabilities to four decimal places.

It is possible with rounding for a probability to be 0.0000. a) State the random variable. Select an answer rv X = the starting salary of a randomly selected nurse rv X = starting salary is normally distributed rv X = the mean starting salary of a sample of nurses rv X = a randomly selected nurse rv X = the mean starting salary of all nurses Correct b) Find the probability that a randomly selected nurse has a starting salary of 91168.4 dollars or more. Incorrect c) Find the probability that a randomly selected nurse has a starting salary of 91698 dollars or less. Incorrect d) Find the probability that a randomly selected nurse has a starting salary between 91168.4 and 91698 dollars. e) Find the probability that randomly selected nurse has a starting salary that is at most 41861.5 dollars. f) Is a starting salary of 41861.5 dollars unusually lowfor a randomly selected nurse?

Why or why not? Select an answer yes, since the probability of having a value of starting salary at least that high is less than or equal to 0.05 yes, since the probability of having a value of starting salary at the most that value is less than or equal to 0.05 no, since the probability of having a value of starting salary at least that high is less than or equal to 0.05 no, since the probability of having a value of starting salary at the most that value is less than or equal to 0.05 yes, since the probability of having a value of starting salary at least that high is greater than 0.05 yes, since the probability of having a value of starting salary at the most that value is greater than 0.05 no, since the probability of having a value of starting salary at least that high is greater than 0.05 no, since the probability of having a value of starting salary at the most that value is greater than 0.05 Correct g) What starting salary do 74% of all nurses have more than?
