Question 1175952: Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Assume that the population has a normal distribution.
n = 12, = 23.6, s = 6.6, 99% confidence
A. 17.68 < μ < 29.52
B. 17.56 < μ < 29.64
C.18.42 < μ < 28.78
D.17.70 < μ < 29.50

I am assuming x bar is 23.6
half-interval is t(0.995,df=11)*s/sqrt(n)
=3.106*6.6/sqrt(12)
=5.92
That makes the CI (17.68, 29.52)
A
