Construct the indicated confidence interval for the population mean μ using a t-distribution. c=0.80, x =109, s=10, n=10 The confidence level is (___ , ___)
Added by Kristi T.
Step 1
First, we need to find the t-score for the given confidence level (c) and sample size (n). Since c = 0.80, the area in each tail is (1 - 0.80) / 2 = 0.10. With n = 10, the degrees of freedom (df) are n - 1 = 9. Using a t-table or calculator, we find the t-score Show more…
