Imagine the investigation had given each student a choice of four sets of personality characteristics for each sign instead of three. If there is no relationship between personality
characteristics and sign, about what fraction of the students in the class do you expect to pick the
description that astrologists say matched their sign? Why do you think this? (Remember, the
"matching set" is the set of traits that astrologists say matches a person's zodiac sign.)

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
