For each hypothesis test you complete, please answer questions (a) through (i) listed below. (a) What conditions should you check first before you conduct the hypothesis test? (b) Write the null and alternative hypotheses. (c)What type of test are you doing: right-tailed, left-tailed or two-tailed? (d)What formula should be used for the test statistic? (e)What number is the test statistic equal to? (f) Sketch a graph of the p-value (g) What p-value do you obtain? Round to the ten-thousandths. (h) Do you reject the null hypothesis or fail to reject the null hypothesis? Explain. (i) Please write a conclusion sentence, in the context of the problem, that explains to a lay person the result of the hypothesis test. 3. The percentage of physicians who are women is 34.9%. In a survey of 120 physicians employed by a large university health system, 37.5% randomly selected physicians were women. Is there sufficient evidence to conclude that the proportion of women physicians at the university health system exceeds 34.9%? Use a 5% level of significance.
