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.
