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. rv X = the starting salary of a randomly selected nurse Correct

b) Find the probability that a randomly selected nurse has a starting salary of 58824.1 dollars or more.

c) Find the probability that a randomly selected nurse has a starting salary of 64990.2 dollars or less.

d) Find the probability that a randomly selected nurse has a starting salary between 58824.1 and 64990.2 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 low for a randomly selected nurse? Why or why not? Select an answer

g) What starting salary do 49% of all nurses have more than? Round your answer to two decimal places in the first box. Put the correct units in the second box.

Suppose the mean starting salary for nurses is $67,709 nationally. The standard deviation is approximately $10,970....

Suppose the mean starting salary for nurses is $67,709 nationally. The standard deviation is approximately $10,970. Assume that the starting salary is normally distributed. Find the probability that a starting nurse will make more than $88,000. Round to four decimals. P(x > $88,000) = Find the probability that a starting nurse will make less than $58,000. Round to four decimals. P(x < $58,000) = Find the probability that a starting nurse will make between $67,000 and $70,000. Round to four...

The Stanford-Binet IQ test is nationally normed with a mean of 100 and a standard deviation of 15. A principal in an elementary school believes that her students have above-average intelligence and wants verification of her belief. She randomly selects 20 students and checks the student files. You will use a z-test to determine whether the students in this school have above-average intelligence and will summarize your findings in a report. IQ scores for 20 students are found in the...
