The Australian Bureau of Statistics (ABS) collects data on how adults working in South Australia (SA) commute to work. The 2016 census published that 3.76% of these workers travelled to work through active transport. Active transport is dened as running, cycling, walking, skateboarding, or using a scooter to travel to work. The Transport Minister has given a press release claiming that only 1.2% of all SA commuters ride a bicycle to their work. Alfred thinks that more commuters cycle to work than the Transport Minister claims. They conduct a survey to determine how many adults cycle to work in SA. A simple random sample of 555 adult commuters found that 11 adults in SA cycle to work. Does this provide evidence that the proportion of all SA commuters who ride a bicycle to their work is more than 1.2%? Answer this question by completing the following hypothesis testing steps.
