In a hypothesis testing problem, the decision as to whether the null hypothesis should be rejected or not can be made by comparing the level of significance and the observed level of significance. The null hypothesis should be rejected if:

A) the level of significance is bigger than the (nonzero) observed level of significance

B) the level of significance is equal to one half of the (nonzero) observed level of significance

C) the level of significance is smaller than the (nonzero) observed level of significance

D) the level of significance is greater than one half of the (nonzero) observed level of significance

E) none of the above

Answer #1

Solution:

Given: In a hypothesis testing problem, the decision as to whether the null hypothesis should be rejected or not can be made by comparing the level of significance and the observed level of significance.

the observed level of significance is also called as p-value.

If p-value is less than or equal to specified level of significance , we reject null hypothesis.

that is if specified level of significance is bigger than p-value ( he observed level of significance), we reject null hypothesis.

Thus correct answer is:

A) the level of significance is bigger than the (nonzero) observed level of significance

We can setup null and alternative hypotheses for decision making. Remember in hypothesis testing the "equals" part will be with the null hypothesis, so you can have less than or equal to, greater than or equal to, or just equal to when defining the null hypothesis. The alternative hypothesis will be, then, either greater than, less than, or not equal to in relation to the above null criteria. See below for how it looks symbolically for the three possible setups....

Suppose that in a certain hypothesis test the null hypothesis is rejected at the .10 level; it is also rejected at the .05 level; however it cannot be rejected at the .01 level. The most accurate statement that can be made about the p-value for this test is that: p-value = 0.01. p-value = 0.10. 0.01 < p-value < 0.05. 0.05 < p-value < 0.10.

Please answer True or False for the following statements: 1.) In hypothesis testing, if the null hypothesis is rejected, then the alternative or motivated hypothesis must also be rejected. 2.) Under certain conditions, binomial distributions can be approximated by normal distributions. 3.) Using a normal distribution to approximate binomial probabilities is extremely accurate, but takes an excessive amount of time and should be avoided. 4.)
