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:
6
Step-by-step explanation:
b = 2 units
h = 6 units
A=1/2 *b*h
= 1/2 *6*2
= 6
First, replace
and
. Then you have
If we take
, then immediately we see a differential in the numerator in the form of
. So the integral becomes
and evaluates to
making (A) the correct answer.
0.176 can be re-written as;
On simplifying by dividing by 8 , this gives;
