In a particular city, the 74% of houses have basements. For which of the following sample sizes is the sample proportion of houses with a basement most likely to be less than 0.70? (a) n = 10
(b) n = 50
(c) n = 100
(d) n = 1000
(e) Impossible to determine without more information.

And why?

-232

step-by-step explanation:

need more information

step-by-step explanation:

- "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."

answer: your correct answer is b. d.
