The first pic is the question, since I’ve been receiving some incorrect answers from the tutors, I included an example problem in the second pic Sample QuestionFemale Physicians The percentage of physicians who are women is 27.9%. In a survey of physicians employed bya large university health system, 48 of 111 randomly selected physicians were women. Is there sufficient evidence atthe 0.05 level of significance to conclude that the proportion of women physicians at the university health systemexceeds 27.9%?Do not round intermediate steps.(a) State the hypotheses and identify the claim.(b) Find the critical value.(c) Compute the test value.(d) Make the decision.(e) Summarize the results.Explanation(a) State the hypotheses and identify the claim.The null hypothesis H, is the statement that there is no difference between a parameter and a specific value. This isequivalent to p= 0.279.The alternative hypothesis H, is the statement that there is a difference between a parameter and a specific value.In this case, the proportion of women physicians at the university health system exceeds 27.9%. This is equivalentto p>0.279.The problem asks, "Is there sufficient evidence at the 0.05 level of significance to conclude that the proportion ofwomen physicians at the university health system exceeds 27.9%?"Hence, the claim is the alternative hypothesis H-(b) Find the critical value.From the figure, for a right-tailed test with a= 0.05, the critical value is z=1.65.a=0.10, C.V.--1.28Summary ofHypothesisTesting andY= ri : Ha = 0.05, C.V.- 1.65H :ukH, : u>k a=0.05, C.V.=+1.65a=0.01, C.V.- +2.33(b) Right-taileda-0.10, C.V.-±1.65H:u=ka= 0.05, C.V.-±1.96a=0.01, C.V.-12.58(c) Two-tailed(c) Compute the test value.First, it is necessary to find p. p, and q.48II-0.432p = 27.9%=0.279q-1-p-1-0.279=0.721Using the formula for the z test for proportions, compute the test value:Vpg/n0.432 - 0.279V(0.279) (0.721)/111= 3.59 Female Physicians The percentage of physicians who are women is 27.9%.
