Question 1177045: 2.) A laboratory in Florida is interested in finding the mean chloride level for a healthy resident in the state. A random sample of 70
healthy residents has a mean chloride level of 104 mEqL. If it is known that the chloride levels in healthy individuals residing in Florida have a standard deviation of 38mEqL, find a 90% confidence interval for the true mean chloride level of all healthy Florida residents. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.

Hi
population chloride levels in healthy individuals residing in Florida:  σ = 38
n = 70, x̄ = 104
90% confidence interval for the true mean
 
ME = = 7.4714

104- 7.5 <  < 104 + 7.5 

CI: (96.5 , 111.5 )

Wish You the Best in your Studies.
