- What do you need to be able to perform a hypothesis test?Hello again, I uploaded a photo containing hypothesis testing problem. Can you pls answer it with a step-by-step solution showing how to get the p-value and critical value approach using and without using excel?In performing a hypothesis test, one should decide whether to reject or not reject the null hypothesis before summarizing the results. True or false. Explain.
- Recognize when to use a hypothesis test?When conducting a hypothesis test, the model used for the test assumes the null hypothesis is true. assumes the null hypothesis is false. assumes the alternative hypothesis is true. makes no assumptions regarding either the null or alternative hypotheses.What is meant when we say that a hypothesis test is a. exact?b. approximately correct?
- 7 step in hypothesis testing with any real world scenario related to restaurantWhat are the two decisions that you can make from performing a hypothesis test? What are the two decisions that you can make from performing a hypothesis test? Select all that apply. A. reject the alternative hypothesis B. make a type I error C. accept the alternative hypothesis D. reject the null hypothesis E. accept the null hypothesis F. fail to reject the alternative hypothesis G. fail to reject the null hypothesis H. make a type II errorThe director of research and development is testing a new drug. She wants to know if there is evidence at the 0.02 level that the drug stays in the system for more than 382 minutes. After performing a hypothesis test, she decides to reject the null hypothesis.
- In the process of completing a hypothesis test, when it comes to decide if we should "Reject the Null Hypothesis" or if we "Do Not Reject the Null Hypothesis", how can we use the P-value to help make our decision? Choose the correct answer to fill in the blank. If our p-value is (less than/ greater than) _________________ the signicance level (?), then we (Reject the Null Hypothesis/ Do Not Reject the Null Hypothesis) _____________________.Are you using a one-sided (directional) or two-sided (non-directional) alternative hypothesis? Explain why you are using that kind of hypothesis. Null Hypothesis H0:μ=3H0:μ=3 Alternative Hypothesis H1:μ≠3Define what a hypothesis is and how it is used in the research process. How are hypotheses tested? What does it mean if a hypothesis is accepted or rejected?
