- Hello. Can you help me answer this question please with a Solution to explain how you got the answer. I was struggling w/ this subject and I hope u can help me. Just a simple solutions/explanations will do. Thank u so much.Please help! :< STATISTICS AND PROBABILITY (PLEASE SHOW your COMPLETE & CLEAR solutions) RATE WILL BE GIVEN The owner of a fast-food shop claims more than 45% of the household within 5-kilometer radius of the fast-food shop have at least one member who eats at the fast-food shop at least once a week. In a sample of 150 households in the area, an investigator found that members of 60 households did so. Do these data provide sufficient evidence to support the fast-food shop owner’s claim? Use 95% level of confidence. Answer the following: a. State the null and alternative hypothesis (in words and in symbols) and identify the claim. b. Find the critical value/s. c. Compute the test value. d. Make the decision (include a normal curve to show where the test value falls). e. Summarize the results.Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim(Don’t just say Reject the null hypothesis or fail to reject the null hypothesis). If you used the calculator, identify everything mentioned above in addition to which calculator functions and inputs for each field were used. In a clinical study of an allergy drug, 108 of the 202 subjects reported experiencing significant relief from their symptoms. At the 0.01 significance level, test the claim that more than half of all those using the drug experience relief.
- Under what circumstances are post tests necessary? When you fail to reject the null hypothesis with more than 2 treatment conditions When you fail to reject the null hypothesis with exactly 2 treatment conditions When you reject the null hypothesis with more than 2 treatment conditions When you reject the null hypothesis with exactly 2 treatment conditions 0000Claim that the standard deviation is at least 25. Express the null hypothesis and the alternative hypothesis in a symbolic form.A null and alternative hypothesis are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Ho: ≤7.3 H₂ Ha µ> 7.3 What type of test is being conducted in this problem? O A. Left-tailed test OB. Right-tailed test OC. Two-tailed test 194
