Construct the indicated confidence interval for the population mean $\mu$ using the $t$ distribution. $$c=0.90, \bar{x}=12.5, s=2.0, n=6$$
Added by Wendy S.
Step 1
The degrees of freedom is n-1 = 6-1 = 5. For a 90% confidence level, the t-value (from the t-distribution table) is approximately 2.015. Show more…
