Be sure to label each with the percent sign! Car = Bus = Train = Give the conditional distribution of mode of transportation for those in management (to the nearest tenth of a percent). Be sure to label each with the percent sign! Car = Bus = Train = Give the conditional distribution of mode of transportation for those in labor (to the nearest tenth of a percent). Be sure to label each with the percent sign! Car = Bus = Train =

Explanation / Answer

marginal distribution:

Car=82/420=0.195~19.5%

Bus=126/420=0.30~30%

Train =212/420=0.505~50.5%

Condition distribution for those in management:

Car=26/90=0.289~28.9%

Bus=20/90=0.222~ 22.2%

train =44/90=0.489~48.9%

Condition distribution for those in Labor:

Car =56/330=0.170~17.0%

Bus=106/330=0.321~32.1%

Train =168/330=0.509~50.9%
