The following gives information about the proportion of a sample that agree with a certain statement. Use StatKey or other techn

marishachu [46]

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

Arrange the list of numbers in increasing order.. . 2/5, 4/9, 3/7

Allushta [10]

The numbers given in the question are 2/5, 4/9 and 3/7. We have to take them to decimal form for arranging the numbers in increasing order.
2/5 = 0.40
4/9 = 0.44
3/7 = 0.43
Then, the increasing order of the numbers would be
2/5 < 3/7 < 4/9
I hope the answer has helped you.
