A researcher was tasked with determining whether the video display used by travel agents for
booking airline reservations should be in color or in black and white. Market research has shown that
travel agencies were primarily concerned with the speed at which reservations can be made.
Therefore, the question was whether color displays
allow travel agents to book reservations faster. Fifty subjects were tested with color displays (x-bar = 503 sec, s = 9.3 sec) and fifty subjects were tested with black and white displays (x-bar = 508.2 sec, s = 9.0 sec). Test if the reservations made on the color displays were significantly faster (less time) than those made on the black and white displays at a significance level of 0.05.
