Question 6 4 pts Now you will compare the results for a different question to determine that the opinions of American adults have changed over the last decade. Tell me if you agree or disagree with this statement: Most men are better suited emotionally for politics than are most women. Success = Agree. Year 2008: 331 successes out of a sample size of 1329 Year 2018: 207 successes out of a sample size of 1558 Careful - questions and numbers may change for different attempts at the lab 1. MAKE A 95% Confidence Interval for Pi - P2 with the artofstat.com app called Compare Two Proportions. Using the option to enter data as Number of Successes, enter the values given above and make the interval. Take a SCREEN SHOT of the results and paste them on a document 2. CONDUCT a Significance Test for Pi-P2 using the same app by changing from Confidence Interval to Significance Test. You will need to enter the correct sign of the alternative hypothesis. Take a SCREEN SHOT of the results and paste them on the same document as the CI. 3. TYPE YOUR INTERPRETATION of BOTH the confidence interval and the p-value on the same document. 4. WRITE A HEADLINE that could be used in an article summarizing your results and type it on the same document. 5. SAVE the document as a PDF FILE. 6. UPLOAD THE FILE that includes the results of the Cl, the results of the significance test, your interpretations of them and the headline. Upload Choose a File

please rate me high.

we have year 2018 data 2008 : n, = 1329 X, - 3.31 m2 = 1558 *2= 207 f = Â = ni ê = 0.2491 5 0.1329 Pi - Pz = 0.249)-013292 0:11.62 | PU-PV) 8, Cl-P... o Quy - 7.4 vniņ2 .
