- Recently, a large academic medical center determined that 7 of 15 employees in a particular position were male,whereas 56% of the employees for this position in the general workforce were male. At the 0.01 level of significance, is there evidence that the proportion of males in this position at this medical center is different from what would be expected in the general workforce? What are the correct hypotheses to test to determine if the proportion is different? A. H0:π≥0.56; H1:π<0.56 B. H0:π=0.56; H1:π≠0.56 C.H0:π≤0.56; H1:π>0.56 D.H0:π≠0.56; H1:π=0.56 Part 2 Calculate the test statistic. ZSTAT=enter your response here (Type an integer or a decimal. Round to two decimal places as needed.) Part 3 What is the p-value? The p-value is..... (Type an integer or a decimal. Round to three decimal places as needed.)

Suppose of the 268 participants surveyed about their drinking habits that reported binge drinking behaviors, 94 were female. Is there statistically significant evidence at the alpha level of 0.05 that males partake in binge drinking behaviors more so than females involved in Greek life organizations? Write out your null and alternative hypotheses and interpret your results. A. Hypotheses: H0: p=0.50 and Ha: p<0.50 B. Test Statistic: (Normal approximation to the binomial is used) ���^ = 0.03054 zstat= -4.88678 C. P-value: P < 0.0002 D. Significance level: Are the results significant?

- If, in a one-tail hypothesis test where H0 is only rejected in the upper tail, the p-value=0.2047 and ZSTAT=+0.82, what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision?there is 0.01 and 0.05 alpha level, what is the critical cutoff z scores for both? which one is easier to reject the null hypothesis and why?A humane society claims that less than 71% of households in a certain country own a pet. In a random sample of 400 households in that country, 276 say they own a pet. At alpha = 0.01, is there enough evidence to support the society's claim? What is the standardized test statistic z? What is the p-value? Do you reject or fail to reject the null hypothesis? Why? How do you enter this problem into a ti84 calculator?
- In a recent study of a random sample of 113 people, 92 reported dreaming in color. In the 1940’s, the proportion of people who reported dreaming in color was 29%. Is there evidence to show that the proportion of people who dream in color is different than the proportion in the 1940’s? What is the decision for this hypothesis test? A) Fail to reject Ho because the test statistic is in the rejection region and the p-value is greater than alpha. B)Fail to reject Ho because the test statistic is not in the rejection region and the p-value is greater than alpha. C) Reject Ho because the test statistic is in the critical region and the p-value is less than alpha. D) Fail to reject Ho because the test statistic is in the critical region and the p-value is less than alpha. E) Reject Ho because the test statistic is in the rejection region and the p-value is greater than alpha.In a survey taken in 2020, 20 out of 50 women and 17 out of 45 men said that they felt our country was headed in the wrong direction regarding universal health care. Do these data provide sufficient evidence at the 0.01 level of significance to conclude that the proportions of women and men that feel out country is headed in the wrong direction regarding healthcare are equal? Use the P-Value Method of Testing. In your work space below, you will need to have -1. The null hypothesis, Ho 2. The alternative hypothesis, H1 3. The test statistic 4. The type of test(left, right, two-tailed) and the p-value 5. The decision to accept Ho or reject Ho
