Question 1043995: Construct the confidence interval for the population mean μ.
c=0.98​, x overbar=15.7​, σ=9.0​, and n=50
A 98​% confidence interval for μ is? ​Round to one decimal place as​ needed

You can put this solution on YOUR website!
Formula for confidence interval is:
x-bar (+/-) z0.01 (sigma)/sqrt(n)
In this case
15.7 (+/-) z0.01(9)/sqrt(50)
