The First National Bank of Wilson has 700 checking account customers. A recent sample of 50 of these customers showed 29 have a
attashe74 [19]

The margin of error is 0.137 and the confidence interval for the population proportion is (0.443, 0.717).

<h3>What is the margin of error(MOE)?</h3>

It is defined as an error that provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

\rm MOE = Z\times \dfrac{s}{\sqrt{n}}

Where   Z is the z-score at the confidence interval

            s is the standard deviation

            n is the number of samples.

We have:

n = 50, X = 29,

Estimate point p = 29/50 = 0.58

q = 1-p = 1-0.58 = 0.42

Z at 0.05/2 (95% confidence interval) = 1.96

\rm MOE = 1.96\sqrt{\dfrac{0.58\times0.42}{50}}

After calculating:

MOE = 0.137

Confidence interval will be: (p - MOE, p+MOE)

= (0.58-0.137, 0.58+0.137)

= (0.443, 0.717)

Thus, the margin of error is 0.137 and the confidence interval for the population proportion is (0.443, 0.717).

how do you find the surface area of a rectangular box with length 10 inches,width 6 inches and height 4 inches
ipn [44]
SA = (Base Area • 2) + (Base Perimeter • Distance)

= (10*6 * 2) + (10 + 10 + 6 + 6 * 4)
= (60 * 2) + (32*4)
=120 + 128
SA = 248 inches squared

Amount of water after splash = 25(4/5) = 20L

Amount of water after Tina adds water = 20L + 7L = 27L
