Answer:

Another rational number

Step-by-step explanation:

Here, we want to get the type of number that should be added to a rational number to explain that the sum of two rational numbers is rational

What we simply have to do here is to add another rational number to the rational number we have already

By adding another rational number to the rational number we have, we will get another rational number

zmey [24]

Answer:

Option D) 0.014

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 1200

Sample proportion =

$\hat{p} = 0.47$

We have to make a 95% confidence interval.

Formula for standard error:

$S.E = \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

Putting the values, we get:

$S.E = \sqrt{\dfrac{0.47(1-0.47)}{1200}} = 0.014$

Thus, the correct answer is

Option D) 0.014
