Round your answer to 3 decimal places. Question: Question 24 0.5 pts Find the critical t-value for a 97.8% confidence interval estimation with 7 degrees of freedom. (Round your solution to 4 decimal places) D Question 25 0.5 pts Find the critical z-value for a 95% confidence interval. (Round your solution to 4 decimal places) Question 26 0.5 pts Find the critical t-value for a 98% ...Since 95% is the most common confidence level, we will find the critical value for constructing a 95% confidence interval. For a 95% confidence interval, α = 1 − 0.95 = 0.05, thus α 2 = 0.025. Using the 'Normal Critical Values' applet above, we find that when α 2 = 0.025, zα 2 = 1.96.

The confidence interval is (7 – 2.5, 7 + 2.5) and calculating the values gives (4.5, 9.5).
