Question:
10 points
(a) Find the critical value of t
c
for the confidence level c and the sample size n, noted below , using a two-sided test.
C = 0.80 ; n = 22
(b) Given c = 0.95 ; s = 0.05 ; n = 25 ; x(bar) = 3.5
(i) Find the margin of error.
(ii) Construct the confidence interval for μ using the statistics you have calculated above .
