The magazine Tech Worx reported that 92% 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 210 randomly chosen software engineers, 188 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 92% (a) State the null hypothesis Ho and the alternative hypothesis H, that you would use for the test. Ho: D p H: 0 020 0-0 0-0 X (b) For your hypothesis test, you will use a Z-test. Find the values of up and " (1 -p) to confirm that a Z-test can be used. (One standard is that np2 10 and , (1-p)2 10 under the assumption that the null hypothesis is true.) Here , is the sample size and p is the population proportion you are testing. np=0 X ? n (1-p)= 0 (c) Perform a Z-test and find the p-value. Here is some information to help you with your Z-test. . The value of the test statistic is given by P- P . P (1 - P) n The p-value is two times the area under the curve to the left of the value of the test statistic. Standard Normal Distribution Step 1: Select one-tailed or two-tailed. o One-tailed O Two-tailed Step 2: Enter the test 0.2 statistic. (Round to 3 decimal places. 0.1 Step 3: Shade the area represented by the p- value. -1 X ? Continue Submit Assignment
