Activity 5: What is My Value? Directions: Find the critical value of the following. 1. one-tailed test, o known, 2.9 a=0.01 n=50 0=known Activity 7. Let's Do Sketch! Directions: Sketch the graph given the critical value and rejection region. 1. t-1.771 or t 2 1.771 2. 25-1.28 Activity 8. Think Critically! Directions: Identify the critical value of each given problem. Find the rejection region and sketch the curve on a separate sheet of paper. 1. A fast food restaurant cashier claimed that the average amount spent by the customers for dinner is F125.00. Over a month period, a sample of 50 customers was selected and it was found that the average amount spent for dinner was F130.00. Using 0.05 level of significance, can it be concluded that the average amount spent by customers is more than P125.00? Assume that the population standard deviation is P7.00. 2. According to the radio announcer, the average price of kilogram of pork liempo is more than P210.00. However, a sample of 15 prices randomly collected from different markets showed an average of P215.00 and standard deviation of F9.00. Using 0.05 level of significance, is there sufficient evidence to conclude that the average price of pork liempo is more than F210.00
