ACTIVITY 1 Directions: Complete the statement by filling out the blanks with the words in the box below. o np 2 5 and nq 2 5 o Sample proportion O Proportion z= For 2= Pe Statistical Test o Population proportion A1._ uses the data obtained from a sample to make a decision about whether the null hypothesis should be rejected. A 2. is the as a percentage of a population The formula for the test statistic or z-Test for proportion is 3. The symbol p represents the 4. Since a normal distribution can be used to approximate the binomial distribution when 5. the standard normal distribution can be used to test hypotheses or proportions. ACTIVITY 1 Directions: Read and analyze the given problem below. A. Suppose a political candidate claims the percentage of uninsured drivers in Puerto Princesa City is 30 percent, but as a senior high school student, you believe the percentage is more than 30 percent. 1. Set up your null and alternative hypotheses. (claim) and H, :p_ 2. Find the critical values(s), assuming a = 0.02 and you have a large sample size. The critical value is z= You may write your explanation to support your answer. ACTIVITY 1 Directions: Perform the following steps: a. State the hypotheses and identify the claim. b. Find the critical values(s). c. Compute the test value. d. Make the decision. e. Summarize the results/Draw conclusions Problem 1. An attorney claims that more than 25% of all lawyers advertise. A sample of 200 lawyers in a certain city showed that 63 had used some form of advertising. At a = 0.05, is there enough evidence to support the IMT's claim? Use the P-value method. Use the space that corresponds to each step for your solution. Solution Step 1. State the hypotheses and identify the claim. Step 2. Compute the test value. Step 3. Find the P.value. Step 4. Make the decision. Step 5. Summarize the results/Draw conclusions
