III. ENGAGEMENT (PERFORMANCE TASK) DIRECTION: Answer the following. 1. A sample of size n = 23 is a simple random sample selected from a normally distribution population. Find the value of t such that the shaded area to the left of t is 0.05. 2. A researcher recruits 18 subjects for a study and conducts a two-tailed t-test for a mean using an alpha level of 0.10. Once she conducts her two-tailed t-test and obtains a test statistic t, what critical value should she compare t to? 3. For a t-distribution with 25 degrees of freedom, find the value of t such that the area to the right of t is 0.025. 4. Find the area between 2 and -bos
