Answer:

Margin of error.

Step-by-step explanation:

Given that a tester sets 99% confiidence limits on a certain statistic

A confidence limit for 99% is obtained as

lower bound of confidence interval as Mean - critical 99% *std error and

upper bound of confidence interval as Mean + critical 99% * std error

Thus a confidence interval would be in interval form with lower limit and upper limit and the average of these two limits is the mean.

The absolute difference between either limit and the mean is the value

Critical value for 99% multiplied by Std error of the variable

= Margin of error

Hence answer is margin of error

I found the missing choices:
<span>the standard deviation
the margin of error
the variance
the population mean
</span>
<span>The absolute difference between either limit and the mean is an example of THE VARIANCE.

Variance is defined as the</span><span> average of the </span>squared<span> differences from the Mean. </span>

100 is smaller than 110 by how many percent?
Roman55 [17]

Compare 100 to 110, and see that to go from 100 to 110 is a 10% increase, but to go from 110 back down to 100 is a 9.09% decrease not a 10% decrease

jenyasd209 [6]

Answer:

5.5 gallons

Step-by-step explanation:

set up a proportion; Liters in numerator and Gallons in denominator

let x = approx number of gallons

<u> 21 </u> = <u> 3.8 </u>

x           1

3.8x = 21

x = 21 ÷ 3.8

x ≈ 5.5

Simplify the square root of 40x^4
Otrada [13]

Answer:

4 = 22

Step-by-step explanation:

Factor 40 into its prime factors

          40 = 23 • 5

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          4 = 22

Factors which will remain inside the root are :

          10 = 2 • 5

To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          2 = 2

At the end of this step the partly simplified SQRT looks like this:

        2 • sqrt (10x4)  

Rules for simplifing variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

     (3.1) sqrt(x8)=x4

    (3.2) sqrt(x-6)=x-3

   (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples:

     (4.1) sqrt(x5)=x2•sqrt(x)

    (4.2) sqrt(x-7)=x-3•sqrt(x-1)

Applying these rules to our case we find out that

     SQRT(x4) = x2

  sqrt (40x4) =

       2 x2 • sqrt(10)

Simplified Root :

2 x2 • sqrt(10)
