Question 1165835: construct the indicated confidence interval for the population mean
μ using the t-distribution. Assume the population is normally distributed.
c=0.90,
x=12.51
s=4.0,
n=9

half-interval is t0.95, df=8*s/sqrt (n)
t=1.860
so the half-interval is 1.860*4/sqrt(9)=2.48
the interval is added to and subtracted form the sample mean
(10.03, 14.99)
