Suppose in 2011 a survey of 1154 workers in the city of Montreal found that 268 used public transport to commute to work. Part (a) Estimate the percentage of workers in Montreal who use public transport to commute to work. Give your answer in percentages (without the percentage sign, and to four significant digits). Part (b) Find a 95% confidence interval for the percentage of workers in Montreal using public transport to commute to work. Use the sample proportion in your estimate of the standard error. Provide the upper and lower bounds for your confidence interval. Give your answer in percentages (without the percentage sign, and to four significant digits) (
