Where people turn for news is different for various age groups. A study was conducted on the use of cellphones for accessing news. The study reported that 26% of users from a certain region under age 50 and 17% of users from the region age 50 and over accessed news on their cellphones. Suppose that the survey consisted of 1,100 users under age 50, of whom 286 accessed news on their cellphones, and 900 users age 50 and over, of whom 153 accessed news on their cellphones. Is there evidence of a significant difference in the proportion of users under age 50 and users age 50 years and older that accessed the news on their cellphones. The null and alternate hypotheses are: H0: π1 = π2 H1: π1 ≠ π2 Determine the value of the test statistic ZSTAT
