In a word document use the five – step approach of hypothesis testing
Please present each step in the following order:
Step 1: Formulate the null and alternative hypotheses H0: X-bar post < X-bar pre , HA: X-bar post > X-bar pre
Step 2: Determine the level of significance Right-tailed test α < .05
Step 3: Determine the critical value of the test statistic By using Table A.3 (I have attached table A.3)
Step 4: Compute the test statistic Table 8.3 (I have attached Table 8.3 (Reading Results is the section to be worked only)
Step 5: Make the conclusion in line with the test statistic With respect to the reading performance.
