Thomas collected 29 responses to a survey and used a two-tailed test to establish a significance level of 0.20 and calculate a 90% confidence interval.
Using the t-table (located in the tutorial), what is the critical t-value used for calculating a 90% confidence interval with 28 degrees of freedom?
Homework Answers
Sample size = 29
Degree of freedom = 29-1 = 28
Level of significance =
