Answer:

Confidence Interval is (21.76928571,23.43071429)

Step-by-step explanation:

The Formula we are going to use is:

$P=\mu$ ± $z_{\alpha/2}*\frac{\sigma}{\sqrt{n}}$

Where:

μ is the mean of sample

σ is the standard deviation of population

n is the sample size

z is the distribution

In our case:

μ=$22.60,σ=$2.50

For 98% Confidence level, 1-α=98%

α=2%

α/2=1%=0.01

From Cumulative standardized Normal Distribution table

$z_{\alpha/2}$ =2.326

$P=\mu\±z_{\alpha/2}*\frac{\sigma}{\sqrt{n}}\\P=22.60\±2.326*\frac{2.50}{\sqrt{49}}\\P=22.60\±0.8307142857$

P=23.430714 P=21.769286

Confidence Interval is (21.76928571,23.43071429)

If Wendell creates a scale drawing using the scale 1 inch to 10 feet, what will the dimensions of the deck in the scale drawing

alexdok [17]

The dimensions on the scale drawing would be 1 inch by 0.8 inches.

The scale is 1 in: 10 ft; since the actual width of the deck is 10 ft, then it will be 1 inch on the scale. To find the width:

1/10 = x/8

Cross multiply:
1*8 = 10*x
8 = 10x

Divide both sides by 10:
8/10 = 10x/10
0.8 = x

The width on the scale drawing will be 0.8 inches.
