Module Answer one part and leave the rest for other students. When giving examples, give one example and let someone else give another example. Trivial answers such as "cool" or "l agree" do not count. Civil discourse only, please. Inappropriate comments result in a loss of credit for this discussion.

The null hypothesis must be rejected at a 5% level of significance. The null hypothesis must be rejected at a 1% level of significance. The null hypothesis must be rejected at both a 5% and a 1% level of significance. None of the above. same set For a hypothesis testing problem with a given data set, you have rejected the null hypothesis at a 10% level of significance. For the same data set,
the statistical significance of an observed relationship in a set if sample data is always expressed in?
When testing a new treatment what is the difference between statistical significance can a treatment have statistical significance but not practical significance
What does it mean when the statistical significance = p value is! equal 0.051? Select one: O a. The alternate (research) hypothesis is not rejected. b. The null hypothesis is is not rejected. c. The null hypothesis is rejected. d. none of the above.
. When we carry out a statistical test with significance level α = 5%, the probability of rejecting the null hypothesis when it is true is 5%. Suppose that we independently select 5 random samples of size 100, and for each sample carry out the same statistical test with significance level 5%. We know that the null hypothesis is true. What is the probability that we reject the null hypothesis at most once out of the 5 tests? (a) 0.02...
What are the primary statistical values in research which could be used to reject or retain a null hypothesis?
that's all the data i have. Refer to the data set in the accompanying table. Assume that the paired sample data is a simple random sample and the differences have a distribution that is approximately normal. Use a significance level of 0.01 to test for a difference between the weights of discarded paper in pounds) and weights of discarded plastic (in pounds) E Click the icon to view the data. In this example, He is the mean value of the...
How to do that? Please give me a example. Open your data in Excel and answer the following in complete sentences. In class this week we've learned about chi-squared tests, which allow us to answer more complicated problems with categorical data. 1. Create a contingency table using Carrier and Origin as your columns and rows, respectively. 2. What is the null hypothesis for a test of independence based on this table? For our purposes, we'll pretend this data set is...
1. A. Give an example of dependent samples. B. Give an example of independent samples. C. When do you reject the null hypothesis? D. Why don't we enter a value into the hypothesis in statcrunch (why is it kept at zero)? E. What is the only type of 2 sample mean test do we do?
