- b) By using the phrases “correct decision” or “wrong decision”, complete the decision table for hypothesis testing below. Where the decision is wrong, state the type of error committed. DECISION H0 is false H0 is true Reject H0 Fail to Reject H0View the information below and respond accordingly. When you perform a hypothesis test, there are four possible outcomes depending on the actual truth (or falseness) of the null hypothesis H0 and the decision to reject or not. The outcomes are summarized in the following table: Table 9.2 ACTION H0 IS ACTUALLY True H0 IS ACTUALLY False Do not reject H0 Correct Outcome Type II error Reject H0 Type I Error Correct OutcomeUse the 7 steps in Hypothesis Testing in answering the problems below.
- Write the following five steps of hypothesis test: 1. Set a set of hypotheses 2. Determine rejection rule with a given a (Fa). 3. Compute test statistic (F-Value) 4. Make judgment 5. Interpretation with p-value Utilize excel output to conduct your answers.Which statement is a null hypothesis? Smith’s mathematics class will have a higher score on the Chapter 4 math exam. Smith’s mathematics class will not have a higher score on the Chapter 4 math exam.Use the six steps of hypothesis testing to answer the following question. Remember to determine if the problem is a Z test or T test as that will influence your critical value. You believe a new teachers personality and enthusiasm is increasing student attendance in class.
