The "jettisoned" passengers freeze immediately on exit to space.
In real life this would not happen. The only way to lose heat in space is via radiation which the the slowest way to lose heat. It will generally take about 10-12 hours.
Seven passengers are convinced they are on a prank show, so they eject themselves out into space. They die horrifically, freezing to death instantly. Freezing would be the least of your problems because losing heat in space is quite difficult. The low pressure of the vacuum around you would cause the blood in exposed capillaries in your eyes and mouth to boil, before you froze and if you had any air in your lungs, they would burst.
