A sales report generated by software run by a small rural caf, 'Beautiful Outlier' was taken to analyse dairy-free milk demand by its customers (and therefore allow the caf owner to make more efficient inventory/stock decisions). Of the 350 customers that day, the report listed that 209 ordered a dairy-free alternative such as almond, oat, soy. What is the p (i.e., the sample proportion) of customers who ordered dairy-free milk with their coffee?
