Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level ofsignificance & using the given sample statistics.Claim: p < 0.13; x = 0.05; Sample statistics: p=0.12, n = 25Can the normal sampling distribution be used?A. No, because nq is less than 5.O B. No, because np is less than 5.OC. Yes, because both np and nq are greater than or equal to 5.D. Yes, because pq is greater than α = 0.05.

Sample Size. How does the sample size affect how close to a normal distribution of either sample means or sample proportion will be?
Use technology to help you test the claim about the population mean, u, at the given level of significance, a, using the given sample statistics. Assume the population is nomally distributed. Claim: u> 1230; a = 0.03; o = 209.07. Sample statistics: x= 1251.28, n 250 O A. H,: µ2 1251.28 Hg: µ 1230 Hg: us 1230 O C. Ho us 1251.28 Ha: u> 1251.28 D. Ho: us 1230 Ha: p> 1230 Ο Ε Η : μ2 1230 OF. Ho: u>1251.28 Ha: µ<1230 H3: µS 1251.28 Calculate the standardized test statistic. The standardized test statistic is 1.61. (Round to two decimal places as needed.) Determine the P-value. P= 0.0537 (Round to three decimal places as needed.) Determine the outcome and conclusion of the test. Fail to reject Ho: At the 3% significance level, there is enough evidence to support the claim.

Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level of significance a using the given sample statistics.

Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. z= (Round to two decimal places as needed.) O B. The test cannot be performed.
Let the height data (105)represent sample. Use an appropriate statistical test to check whether the population mean is different from 170 cm.Use α = 0.05.Also, write a substantive conclusion and explanation. Use an appropriate graph to check if data is normally distributed. Do it in R commander.
Which of the following is TRUE about the mean of the sampling distribution of the sample means? It is less than the population mean. It is not related to the population mean. It is equal to the population mean. It is greater than the population mean.
Answer the last question
Does Hypnotism Relieve Pain? The table shows the pain levels of patients before and after hypnotism. Pain level is measured on a cm scale. Assume that the two samples are randomly selected. At the 0.05 significance level, test the claim that the mean difference has increased after hypnotism.(Be sure to subtract in the same direction).
Refer to the data set in the accompanying table. Assume that the paired sample data is a simple random sample and the differences have a distribution that is approximately normal. Use a significance level of 0.10 to test for a difference between the weights of discarded paper (in pounds) and weights of discarded plastic (in pounds). a. Identify the test statistic. t equals (Round to two decimal places as needed.) b. Identify the P-value. P-value equals (Round to three decimal places as needed.)
Please help with part e
Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the given level of significance α using the given sample statistics. Claim: p≠0.21; α=0.05; Sample statistics: p=0.16, n=175 Can the normal sampling distribution be used? A. Yes, because both np and nq are greater than or equal to 5. Your answer is correct. B. No, because np is less than 5. C. Yes, because pq is greater than α=0.05. D. No, because nq is less than 5. State the null and alternative hypotheses. A. H0: p≥0.21 Ha: p<0.21 B. H0: p=0.21 Ha: p≠0.21 This is the correct answer. C. H0: p≤0.21 Ha: p>0.21 Your answer is not correct. D. The test cannot be performed. Determine the critical value(s).
