The percentage of physicians who are women is 32%. In a survey of physicians employed by a large university health system, 48 of 140 randomly selected physicians were women. Is there sufficient evidence at the 0.05 level of significance to conclude that the proportion of women physicians at the university health system exceeds 32%? a. State the hypothesis and identify the claim of the researcher. H: p = 0.32 and H₁: p > 0. 32 (claim) b. Find the critical value(s). Since a = 0.05 and the test is a right-tailed test, the critical value is z = 1.64 c. Compute the test value. d. Make a decision on the null hypothesis. e. Make a decision on the claim of the researcher.
