No explanation is required for this problem. Suppose that you had access to the following data set, called jobdata, with variable labels in the top row. This data set is a random sample of 15,280 members of the Service Employees International Union (SEIU). It records each person's gender, birth date, education level, job category, current salary, starting salary, and time employed. The first two rows are shown below. ID Gender bDate educ Jobcat salary salbegin jobtime prevexp minority 475 10-Feb- 1972 15 1 $102000 $55,000 80 36 f 20-Jul- 1965 m 0 476 16 2 $132000 $70,000 45 100 What sequence of commands (including pipe operators %>%) would you use to obtain a 95 percent confidence interval for the proportion of SEIU workers who are minorities? It's ok to have small typos e.g. a missing parenthesis or comma as long as you have all the inputs and functions you need, in the right order. 1
