Suppose that we are to conduct the following hypothesis test:   H0: μ=1020 H1:  μ>1020 Suppose that you also know that σ=220, n=95,x¯=1053, and take α=0.05. Draw the sampling distribution, and use it to determine each of the following: A. The value of the standardized test statistic:    Note: For the next part, your answer should use interval notation. An answer of the form (−∞,a)(−∞,

Suppose that you want to perform a hypothesis test for a population mean. Assume that the population standard deviation is unknown and that the sample size is relatively small. In each​ part, the distribution shape of the variable under consideration is given. Decide whether you would use the​ t-test, the Wilcoxon​ signed-rank test, or neither.   a. Triangular b. Symmetric bimodal c. Left skewed

Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the giver using the given sample statistics. Claim: p#0.24; a = 0.01; Sample statistics: p = 0.22, n = 200 Can the normal sampling distribution be used? Yes, because both np and nq are greater than or equal to 5. O B. No, because np is less than 5. OC. No, because ng is less than 5. O D. Yes, because pq is greater than a = 0.01. State the null and alternative hypotheses. O A. Ho: ps0.24 H,: p>0.24 B. Họ: p=0.24 Hi p#0.24 OC. Họ: p20.24 H:p<0.24 O D. The test cannot be performed. Determine the critical value(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The critical value(s) is/are - 2.58, 2.58. (Round to two decimal places as needed. Use a comma to separate answers as needed.) O B. The test cannot be performed. Find the z-test statistic. Select the correct choice below and, if necessary, fill in…

Find the test statistic, t, to test the hypothesis that u, = H,. Two samples are randomly selected and come from populations that are normal. The sample statistics are given below. Round to three decimal places. n= 14 X = 21 n2 = 12 X2 = 22 S1=2.5 $2 = 2.8 A. -0.909 B. - 0.954 C. -1.558 D. -0.915 Click to select your answer. 02/16/21 Ch 2.1 Homework P Type here to search 99+ a Gip 立
