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.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
