If the computed test statistic is 1.25. What decision can be made? A. Accept Ho C. Reject Ha B. Accept Ho and Ha D. Reject Ho ACTIVITY 1 Directions: Find and illustrate the appropriate rejection region in each case. The normal curve is provided for you. 1. Hai >Ho, a = 0.01 3. Ha: H # Ho, a = 0.01 2. Ha: HSHo. a = 0.05. ACTIVITY 2 Directions: Given the problem, identify the appropriate It is claimed that the average monthly income of online sellers during the pandemic is P35,600.00. A random sample of 35 online sellers is selected and it is found out that the average monthly income is P35,900.00. Using a 0.01 level of significance, can it be concluded that there is an increase in the monthly income of online sellers? Assume that the population standard deviation is P 270.00. (You may use the steps in the example as your guide.) How do you find the activity? Can you now illustrate the rejection region on your own
