Answer:
99.7% of the sample proportions will fall between 0.133 and 0.307.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 0.22
Standard deviation = 0.029
99.7% of the sample proportions will fall within which of the following intervals?
Within 3 standard deviations of the mean.
Lower end: 0.22 - 3*0.029 = 0.133
Upper end: 0.22 + 3*0.029 = 0.307
99.7% of the sample proportions will fall between 0.133 and 0.307.

Answer: 49.0 square meters
====================================================
Explanation:
We'll first need to find the radius of the rug using the circumference.
C = 2*pi*r
r = C/(2pi)
r = (24.8)/(2*3.14)
r = 3.949045 which is approximate.
Now we can find the area
A = pi*r^2
A = 3.14*(3.949045)^2
A = 48.968163 this is also approximate
Rounding to the nearest tenth gets to 49.0
X) = 3 ln(x)
g(x=2) = 3 ln(2)
g(x=4) = 3 ln(4) = 3 ln(22) = 6 ln2
We have two ordered pairs:
(x,3 ln(2)) and (4,6 ln(2))
The average rate of change is the slope (m) of the secant line connecting the two points:
m = (6 ln2 - 3 ln2)/(4-2) = 3ln(2)/2 ≅ 1.04
