QUESTION 13

  1. A person is conducting a hypothesis test regarding a proportion of a certain population. Suppose they get a test statistic of 1.15. What does this indicate?

A.

They have strong evidence to reject the null hypothesis.

B.

They do not have enough evidence to reject the null hypothesis.

QUESTION 14

  1. A person is conducting a hypothesis test regarding a mean of a certain population. They get a test statistic of 3.42. What does this indicate?

A.

They have strong evidence to reject the null hypothesis.

B.

They do not have enough evidence to reject the null hypothesis.

QUESTION 15

  1. A person is conducting a hypothesis test. Suppose they obtain a p-value of .2261. What does this indicate?

A.

They have strong evidence to reject the null hypothesis.

B.

They do not have enough evidence to reject the null hypothesis.

Answer 13

A person is conducting a hypothesis test regarding a proportion of a certain population. Suppose they get a test statistic of 1.15.

This does not contain proper information about the test. The information about tabulated value of test statistic is missing, so we can't compare the given test statistic value to take any decision.

So, OPTION 'B' is correct.

Answer 14

A person is conducting a hypothesis test regarding a mean of a certain population. They get a test statistic of 3.42.

These does not content proper information about the test the information about the tabulated value of test statistics is missing so we can't compare the given statistics value to take any decision, the significance level of the test is also missing.

so option B is correct

Answer 15

A person is conducting a hypothesis test. Suppose they obtain a p-value of .2261.

p-value is calculated on the basis of the level of significance but here level of significance is missing and we also know that the higher of the p value then we can't reject the null hypothesis

so here option B is correct

Whether we are conducting a hypothesis test with regards to a one population parameter or two population parameters (usually the difference between two population parameters), the concept of p-value is extremely important in making a decision with respect to the null hypothesis. A very common mistake in elementary statistics is interpreting the p-value of a hypothesis test. Many students think that the p-value is the probability that the null hypothesis is true or that it is the probability of rejecting...

Think about a population proportion that you may be interested in and propose a hypothesis test problem for this parameter. Gather appropriate data and post your problem. Include the null and alternative hypothesis, alpha value, p-value, and a conclusion. Make sure that you use appropriate terminology, specify whether you are using the classical method or the p-value method, and fully explain your solution.
