Race relations: a new york times/cbs poll surveyed 1,027 adults nationwide about race relations in the united states. of the sample, 61% responded that race relations in this country are generally bad. the 95% confidence interval is (0.58, 0.64). which of the following is an appropriate interpretation of the 95% confidence interval?

- "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."

1/4 is the asnwer cuz 5/20 is the faction
