Question 1078428: : 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= 10, = 11.3, s =2.4, 95% confidence
A. 9.58 μ 13.02
B. 9.91 μ. 12.69
C. 9.61 μ. 12.99
D. 9.59 μ. 13.01

interval width=t df=9, 0.975*sigma/sqrt(n)=2.26*2.4/sqrt(10)=1.72
11.3+1.72=13.02
11.3-1.72=9.58
(9.58, 13.02)
A
