Extracted text: O CONFIDENCE INTERVALS AND HYPOTHESIS TESTING Julia v Introduction to hypothesis tests for a population proportion usin.. The magazine Tech Worx reported that 91% of software engineers rate the company they work for as "a great place to work." As a veteran headhunter, you claim the percentage given in the report is not correct. In a survey of 220 randomly chosen software engineers, 210 rated the company they work for as "a great place to work." Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to support your claim that the proportion, p, of all software engineers who rate the company they work for as "a great place to work" is not 91%. (a) State the null hypothesis H and the alternative hypothesis H, that you would use for the test. Но: р — 0.91 p O10 under the assumption that the null hypothesis is true.) Here n is the sample size and p is the population proportion you are testing. пр3 п (1-р) -О (c) Perform a Z-test. Here is some information to help you with your Z-test. • Zo os is the value that cuts off an area of 0.05 in the right tail of the distribution. Explanation Check © 2021 McGraw-Hill Education.
