Question

Hi,

How do I calcuate these missing values? 

The Pew Research Center conducted a poll in January 2014 of online adults who use social networking sites. According to this poll, 89% of the 18 – 29 year olds and 82% of the 30 – 49 year olds who are online use social networking sites (www.pewinternet.org). Suppose that this survey included 562 online adults in the 18 – 29 age group and 624 in the 30 – 49 age group. a. Let p, and p, be the proportions of all online adults in the age groups 18 – 29 and 30 – 49 years, respectively, who will use social networking sites. Construct a 90% confidence interval for p, - P2. Round your answers to two decimal places. 0.0368 to 0.1032 b. Using a 2% significance level, can you conclude that p, is different from p,? Use both the critical-value and the p-value approaches. Round your answer for the observed value of z to two decimal places, and the p-value to four decimal places. observed value of z = i p-value = i
