The class president collected data on 150 randomly selected 17-year-olds at his school. He surveyed students on if they had a job and driver's license. The results are shown below.

· 93 of the 17-year olds had a job

· 128 of the 17-year olds had a driver's license

· 76 of the students had both a job and a driver's license

Part A: Construct a two-way frequency table summarizing the data. Since you can't make a table, use the letters a) through i) to label the values when you type your answers.

d) e) f)

g) h) i)

Part B: What percent of the students who have a job, do not have a driver's license?
