Answer #1

Solution :

Given that ,

mean = = 150

standard deviation = = 28

n = 29

= 150

sampling distribution of standard deviation

=  / n = 28/ 29=5.199

Calcium levels in people are normally distributed with a mean of 9.5mg / (dL) and a standard deviation of 0.4 mg / (dL) . Individuals with calcium levels in the bottom 10% of the population are considered to have low calcium levels. Find the calcium level that is the borderline between low calcium levels and those not considered low. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
