go Jack surveyed a random sample of people on the

00:08

street about whether they preferred a winter or summer weather

00:11

and every person responded with one of these two options

00:14

Of the thirty five people he surveyed thirty four point

00:16

three percent said they preferred summer weather if he had

00:19

survey two hundred fifty people approximately how many people would

00:22

preferred summer weather So all we have to do is

00:36

take one minus that point three four three There is

00:41

going to get us about sixty five point seven percent

00:44

which we're going to take as point six five seven

00:46

and multiply by two Fifty to get us the right

those thirty five people are irrelevant So that is thirty

01:17

four point three percent like summer And yes that's a

01:20

sixty five point seven percent like winter So we multiply

01:23

that number by two fifties we said and we get

01:25

the hundred sixty four People would say they prefer winter

01:29
