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 the null hypothesis: Explain why you think many students erroneously come to these conclusions. In your own words, explain what the p-value represents. What pages of the reading in OLI support your explanation?

Think about two population means that you may be interested in and propose a hypothesis test problem for this parameter.
write a hypothesis test problem. Post your problem with a solution. Think about two population means that you may be interested in and propose a hypothesis test problem for this parameter. For example, you may believe that the average family size in Illinois is greater than the average family size in Wisconsin. Your data could be that you spoke with 20 people (10 in Illinois and 10 in Wisconsin) and found the following family sizes: 5, 6, 5, 2, 3,...

If we were to conduct a hypothesis test to test if a population proportion of a certain event is 0.2 versus the alternative that it is greater than 0.2 and we sampled 100 people, what would the probability of a Type I Error be if we were to use the arbitrary decision rule to reject Ho if more than 30 units in the sample had the event (not the way we tested hypotheses in class)? What would the probability of...

In a question involving a hypothesis test having the population mean as the target parameter, you are given the sample size, n, the assumed population mean, the significance of the test, alpha, whether it is a right-tailed, left-tailed, or two-tailed test, and the result of the test (reject or do not reject the null hypothesis.) Show how you can use this information to find bounds on the sample itself. You may put in simple values for the information given if...

QUESTION 13 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 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...

True or False? A hypothesis test is conducted at to test whether the population correlation coefficient is zero. If the sample size is 25 and the sample correlation coefficient is 0.6, then the critical values of the student t that define the upper and lower tail rejection areas are 2.069 and -2.069, respectively.

We when run a hypothesis test, we are looking to verify a claim about a population parameter. Why is it important that we have a statistical tool to allow us to do this? For example, suppose that you were the quality control officer for a CPU manufacturer. Your job is to ensure that the CPUs your company makes meet certain performance standards so that when they are installed in iPhones they function properly and the phone company can truthfully claim...

A hypothesis will test that two population means are equal. A sample of 10 with a standard deviation of 3 is selected from the first population and a sample of 15 with a standard deviation of 8 from the second population. The standard deviations are not equal. Testing the claim at the 0.01 level, what is the critical value? Assume unequal standard deviations. Please explain and show your work. Thank you!

What do we mean by critical values for significance in a hypothesis test for the population​ proportion? How does this compare to the critical values for statistical significance for a population​ mean? How do we use this for making decisions about the hypothesis​ test? What do we mean by critical values for significance in a hypothesis test for the population​ proportion? A. The critical values are the standard scores required for statistical significance at a given level. B. The critical...
