Question

A study resulted with a z_obt = +2.34. z_crit was ±2.03 with α = .05. Based on these results, A) we should fail to reject H₀. B) we should reject H₁. C) p > .05 D) p < .05

Quizplus · Accepted Answer

The z-score of 2.34 is greater than the critical z-score of 2.03 with a significance level of 0.05. This means that the probability of obtaining a z-score of 2.34 or higher under the null hypothesis is less than 0.05, which is the level of significance. Therefore, we reject the null hypothesis and conclude that the alternative hypothesis is true with a significance level of 0.05. This also means that p < 0.05.
