Explain the four steps of hypothesis testing.

Answer to Problem 1FP
The four steps of hypothesis testing are (1) Stating the hypotheses, (2) Set the criteria for decision, (3) Compute the test statistic and (4) making a decision.
Explanation of Solution
Four steps of Hypothesis Testing:
Step 1: State the hypotheses.
Step 2: Set the criteria for a decision.
Step 3: Compute the test statistic.
Step 4: Make a decision.
Justification: The hypothesis testing can be done in four steps. The null and alternative hypothesis can be defined in the first step for testing the given claim, the criteria for making the decision based on level of significance is defined in second step. After defining the criteria, the test statistic can be computed in third step to make the conclusions. Finally decision about either rejecting or retaining the null hypothesis is made in the fourth step.
Hence, the four steps of hypothesis testing are (1) Stating the hypotheses, (2) Set the criteria for decision, (3) Compute the test statistic and (4) making a decision.

- To evaluate the success of a 1-year experimental program designed to increase the mathematical achievement of underprivileged high school seniors, a random sample of participants in the program will be selected and their mathematics scores will be compared with the previous year’s statewide average of 525 for underprivileged seniors. The researchers want to determine whether the experimental program has increased the mean achievement level over the previous year’s statewide average. If alpha=.05, what sample size is needed to have a probability of Type II error of at most .025 if the actual mean is increased to 550? From previous results, sigma=80.arrow_forwardPlease help me answer the following questions from this problem.arrow_forwardPlease help me find the sample variance for this question.arrow_forward
