Question

A researcher calculates a mean from a sample of 19 people. For α = .05, if the researcher states the hypotheses as H₀: µ = 200 and H₁: µ < 200, which of the following is an appropriate critical value?

A) 0.688
B) 1.645
C) 1.734
D) 1.729

Country Shine · Accepted Answer

Final Answer : C, Explanation :  Given that the sample size is 19 (which means degrees of freedom = 18) and the test is one-tailed with α = .05, the appropriate critical value from the t-distribution table for a one-tailed test with these parameters is approximately 1.734.
