A) 1.734
B) 2.110
C) 2.101
D) 2.086

Question

destiny graham · Accepted Answer

Final Answer : B, Explanation :  Given that the sample size is 18, the degrees of freedom for the t-test would be 17 (n-1). For a two-tailed test with α = .05, the critical value from the t-distribution table for 17 degrees of freedom is approximately 2.110.
