4. Researchers believe that men are more physically aggressive than women. To test this, researchers ask 20 participants (10 male, 10 female) to rate how aggressive they are on a scale from 1 to 10. Their scores are listed below. Conduct all six steps of hypothesis testing (use p=.05). Be sure to label all six steps. Also, include a concluding statement (which should include the effect size).

2. A study performed in 2010 found that 4% of people with asthma have aspirin sensitivity. A hospital suspects that the percentage may actually be higher and tests a random sample of 310 asthma patients in controlled conditions. The hospital found that 20 out of the 310 asthma patients they tested had aspirin sensitivity. At the 0.05 significance level, test the claim that more than 4% of all asthma patients have aspirin sensitivity. a. State the i. Claim in words ii. Express the claim mathematically iii. What is the Null Hypothesis iv. What is the Alternative Hypothesis b. Which test procedure is appropriate to perform the required hypothesis test? c) Compute the value of the test statistic. d) What is the P-Value. Please round your P -value to three decimal places. P-Value = e) Should you reject the null hypotheses or not? f) What is your conclusion about the hypothesis test?

10) In a survey of 500 cigarette smokers, 39 of them reported that they have tried hypnosis therapy to try to quit smoking.. Can you conclude that less than one-tenth of smokers have tried hypnosis therapy? Use the a = 0.05 level of significance. %3D A) No B) Yes C) No conclusion is possible.
Past studies have indicated that the percentage of smokers was estimated to be about 34%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 1807 people and found that 574 smoke. Use a 0.05 significance level to test the claim that the percentage of smokers has reduced. a) Identify the null and alternative hypotheses? Но: ? H1: ? v b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? O left-tailed O right-tailed O two-tailed c) Identify the appropriate significance level. d) Calculate your test statistic. Write the result below, and be sure to round your final answer to two decimal places. e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places. f) Do you reject the null hypothesis? O We reject the null hypothesis, since the p-value is less than the significance level. O We reject the null hypothesis,…
