Critical value z_{0.05}=-1.645
Decision Rule, Reject H if z< -1.645
We do not reject the null hypothesis.
<h3>What is the
Decision?</h3>
Generally, the equation for the hypothesis is mathematically given as
H P=0.3
H2:P<0.13
Therefore
![z=\frac{p'-p}{\sqrt{\frac{p(1-p)}{n}}}\\\\\\z=\frac{0.11-0.13 }{\sqrt{\frac{0.13(1-0.13)}{76}}}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bp%27-p%7D%7B%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%7D%7D%5C%5C%5C%5C%5C%5Cz%3D%5Cfrac%7B0.11-0.13%20%7D%7B%5Csqrt%7B%5Cfrac%7B0.13%281-0.13%29%7D%7B76%7D%7D%7D)
z=-0.52
In conclusion, from the table
Critical value z_{0.05}=-1.645
Decision Rule, Reject H if z< -1.645
In conclusion, we do not reject the null hypothesis.

Answer:
B. 72
Step-by-step explanation:
The rule of 72 is used as a rough estimate of the number of years required for an investment to double.
According to this rule, the number of years 'n' necessary to double an investment at an annual rate 'r' is:
![n=\frac{72}{r}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B72%7D%7Br%7D)
Therefore, the number that when divided by the interest rate gives the number of years required to double an investment is 72.
The answer is B. 72.
Answer:
well, took me some time but I did answer all of em
Answer:
15
Step-by-step explanation:
(-2,3)-x1,y1
6,r -x2,y2
slope(m)=3/2
m= y2-y1/x2-x1
3/2= r-3/8
r=15
Answer:
C=401.92
Step-by-step explanation:
the equation for area of a circle is A=r^2 pi so if the area of this circle is A=64^2 pi, then we can see that 64 is the radius of the circle.
(A=r^2 pi
A=64^2 pi so r=64)
So if the radius is 64, then the diameter is (because diameter is double the radius) Then we use the newfound diameter and plug into the equation for Circumference of a circle which is
C=d pi
C=128 (3.14)
so C=401.92
Hope this helps! :)
