What is the median for the set of data?

1 answer:

Masteriza [31]2 years ago

6 0

Answer:

2

Step-by-step explanation:

2 because it is the middle one and to do the median you have to put the numbers in order so for example, smallest to biggest vice versa and then cross the numbers from each side until you find the middle and if there is one then that is the median and if there is two then you add them together and then divide by 2.

Answer:

(0.2278, 0.3322)

Step-by-step explanation:

Given that out of 400 people 112 agree and 288 disagree

Proportion of people agreeing = $\frac{112}{400} =0.28$

$q=1-p =0.72\\se = \sqrt{\frac{pq}{n} } =0.03175$

For confidence interval 90% we have critical value as

1.645

Margin of error =1.645*SE

= $1.645(0.03175)\\= 0.0522$

Confidence interval $= (0.28-0.0522, 0.28+0.0522)\\= (0.2278, 0.3322)$
