Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: p=0.84 versus H,: p+0.84 n= 500, x = 410, a = 0.01 Is npo (1- Po) > 10? Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) O A. Yes, because npo (1-Po) =|: O B. No, because npo (1- - Po) =

PART II. HYPOTHESES TO TEST Below are a series of hypotheses to be tested. I have done one sample to show you the format in which I want you to do all problems. Follow the example in doing each problem. Steps to follow in doing problems Please give the following steps for each problem: a) if not given in the problem, state the nul and altemative hypotheses b) indicate whether you have a one- or a two-tailed test situation c) give the formula for the test statistic you will use d) diagram the null sampling distribution e) state a decision rule and diagram values for which you will or will not reject Ha 1 calculate the standard error and the test statistic; state the statistical decision to reject or not reject Ho g) briefly state in words what the outcome of the test is Example Problem. You have devised a new approach to testing IQ in young children. You believe that your testing method will produce dfferent results from the usual tests now in use. The usual tests give p= 100 and s = 15…

Non-Parametric StatisticsIdentify the hypotheses (in words and symbols), the test statistic or method applicable, the decision rule, the computation to determine the test statistic, the decision, and the conclusion. Show all your solutions and round off your answers up to 4 decimal places
Original claim: Half of cell phone owners have apple iPhones. Initial conclusion: Fail to Reject H0. Fill in the blanks to finish the conclusion: There enough evidence to the claim that most people own apple iPhones.
Please help me find THE BEST CORRECT answer
State the hypothesis and identify the directional test. In this example, the null hypothesis is Ho = 120,000. You may notice that the hypothesis used the phrase 'greater income' that is associated with greater than. Therefore, H, >120,000. This hypothesis uses inequality symbol (>) so it is one-tailed test and it uses greater than which specifically called for the right-tailed test. Họ : R= 120,000 and Hạ : l>120,000 (right-tailed test) 3. The average waiting time of all costumers in a restaurant before being served is less than 20 minutes. Determine the hypotheses and the directional test. You may notice that the hypothesis used the phrase 'less than' which denotes that the alternative hypothesis is Ha 121 Alternative Hypothesis: 4. The Bureau of Internal Revenue claims that the mean wait time for taxpayers during a recent tax filing is at most 8.7 minutes. A random sample of 11 taxpayers has a mean wait time of 8.7 minutes and a standard deviation of 2.7 minutes. Is there enough…
