In response to the COVID-19 pandemic, Australian federal government developed COVIDSafe app (https://www.health.gov.au/resources/apps-and-tools/covidsafe-app) which uses mobile tracking technologies to perform rapid contact tracing. However, these technologies are only effective if the public is willing to use them, implying that their perceived public health benefits must outweigh personal concerns over privacy and security. The current study assessed attitudes towards the COVIDSafe app in a representative sample of the Australian public. Participants were invited to a survey. After providing consent and demographic information, participants were asked about how they perceived the risk of COVID-19, perceived benefits and harms from smartphone tracking. Responses were made on a 5-point Likert scale, where increasing values were associated with greater endorsement of the issue raised in a specific question. Based on the above information, answer the following: (1 mark) What type of study is this? Answer 1 Question 1 (1 mark) What is the population of interest? Answer 2 Question 1 (2 mark) What is NOT a variable of interest
