Find the 95% confidence interval for the proportion of customers planning to buy the shoes, and interpret your answer in context. Show all the steps of your calculations, with clear justification where necessary, and include any formulas used. Round the numbers at each step to 3dp.
Unitary Method

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
