- ) Consider the following figures showing the situation of the Australian labourmarket in 2018 (figures are per thousand and in percentage).Employed persons ('000) 12 620.7Unemployed persons ('000) 711.9Unemployment rate (%) 5.4Participation rate (%) 65.6a. What is the labour force participation rate? Briefly checking some online sources is it lower or higherthan in other countries? Try to provide some explanation for the difference.b. Assume that the participation rate in Australia changes to 63%, but the adult population and the numberof employed remain unchanged (hint: if the adult population is not reported, you can calculate it easilyfrom the labour force and participation rate). What would be the labour force, the number ofunemployed, and the unemployment rate?c. Go to the latest LFS by the ABS at: www.abs.gov.au/ausstats/abs@.nsf/mf/6202.0. How does the currentsituation compare with 2018? Spend about 10 minutes going through the website and report at least oneobservation you find…Social media is popular around the world. Statista provides estimate of the number of social media users in various countries in 2017 as well as the projections for 2022. Assume that the results for surveys in the United Kingdom, China, Russia, and the United States are as follows.The article “Credit Card Activity for College Students“ ( wallethub.com/edu/credit-card-statistics-for-college-students/25535/, Retrieved February 13, 2018)estimated that in 2013, 62% of undergraduates with credit cards pay them off each month and that the average outstanding balance on undergraduates’ credit cards is $650. These estimates were based on an online survey of 800 college students. What additional information would you want in order to decide if it is reasonable to generalize the reported estimates to the population of all undergraduate students?
