Question

Suppose that blood chloride concentration (mmol/L) has a normal distribution with mean 105 and standard deviation 5.

(a)

What is the probability that chloride concentration equals 106? Is less than 106? Is at most 106? (Round your answers to four decimal places.)

equals 106less than 106at most 106

(b)

What is the probability that chloride concentration differs from the mean by more than 1 standard deviation? (Round your answer to four decimal places.)

Does this probability depend on the values of μ and σ?

---Select--- Yes No , this probability  ---Select--- does does not depend on the values of μ and σ.

(c)

How would you characterize the most extreme 0.6% of chloride concentration values? (Round your answers to two decimal places.)

The most extreme 0.6% of chloride concentrations values are those less than  mmol/L and greater than  mmol/L.

You may need to use the appropriate table in the Appendix of Tables to answer this question.
