Self-isolation for Coronavirus

In the context of the current pandemic situation, the Orlando Health Agency (OHA) was

interested to know how Orlando residents support their recommended self-isolation instructions related to the novel Coronavirus. They commissioned a professional agency to a

survey of 1000 individuals living in the city in March 2020 and obtained the following results:

Support of OHA Self-Isolation Instructions

Returning Travellers 69 81 150

(a) [1]What is the population of interest?

(i) Orlando residents who participated in the survey

(ii) Orlando residents in March 2020

(iii) Orlando citizens

(b) [1]What is the appropriate statistic for assessing the support for OHA recommended

self-isolation instructions related to novel Coronavirus?
