Answer #1

Solution:
Its correct answer is D. i.e. the probability of rejecting the Null hypothesis H0 given that the null hypothesis H0 is true.
So Correct interpretation of the significance level α in a hypothesis test is the probability of rejecting H0 given that H0 is true. Its the probability of making a wrong decision.
Let's assume alpha = 0.05 which indicates a 5% risk of conducting that a difference exists when there is no actual difference.
So its correct answer is D. i.e. the probability of rejecting H0 given that H0 is true.

In a two-tailed hypothesis test of the mean using a 0.05 level of significance, researchers calculated a p-value of 0.03. What conclusion can be drawn? The alternative hypothesis should be rejected because the p-value is so small. The null hypothesis is true because the p-value is less than the level of significance. The alternative hypothesis is 3% likely to be true. The null hypothesis should be rejected because the p-value is less than the level of significance. 1.The alternative hypothesis...
