Answer:

Step-by-step explanation:

The larger the sample size, the lower the standard deviation. The standard deviation shows how the data is spread from the mean. Therefore, benefit of increasing the sample size when trying to estimate the mean from a sample average are

a. A reduction in the bias of the estimate.

b. A reduction in the variability of the estimate.

The width of confidence interval is determined by the margin of error

Margin of error = z × s/√n

A smaller standard deviation and increased size would result to a narrower confidence interval. Therefore, increasing the sample size does not result to an increase in the width of the resulting confidence interval.

One question, seventh grade question, please help! It’s not long!
vfiekz [6]

Answer:

The Correct Answer Is 4

Step-by-step explanation:

So if you have $12 and you can buy $3 with each box of envelopes, you think, how many times can 3 go into 12

count in your head, 3 6 9 12 therefore, ITS 4

here is your equation to match this:

3 x ? = 12

You probably already know this, but i simple way to figure this out is to flip the equation to

12/3 = ?

so from here you can tell that 3 goes into 12 4 times

so the equation is

3 x 4 = 12

Hope It helps!

Describe the roots of the equation shown below.
Olegator [25]

Answer:

B. There is one real, double root

Step-by-step explanation:

For ax² + bx + c = 0, the discriminant is b² − 4ac.

If the discriminant is positive and a perfect square, there are two real, rational roots.

If the discriminant is positive and not a perfect square, there are two real, irrational roots.

If the discriminant is 0, there is one real, double root.

If the discriminant is negative, there are two complex roots.

Here, a = 64, b = -16, and c = 1.

b² − 4ac

= (-16)² − 4(64)(1)

= 0

The discriminant is 0.  Therefore, there is one real, double root
