It’s 60 feet away from the cliff because it has a height of 70 feet tall
Answer:
The sample needed is 
Step-by-step explanation:
From the question we are told that
The margin of error is 
The confidence level is 
Given that the confidence level is 95% the level of significance is mathematically represented as


Next we obtain the critical value of
from the z-table , the value is 
The reason we are obtaining critical value of
instead of
is because
represents the area under the normal curve where the confidence level interval (
) did not cover which include both the left and right tail while
is just the area of one tail which what we required to calculate the margin of error
The sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \r p[1-\r p]](https://tex.z-dn.net/?f=n%20%20%3D%20%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%5Cr%20p%5B1-%5Cr%20p%5D)
Here
is sample proportion of people that supported her and we will assume this to be 50% = 0.5
So
![n = [\frac{1.96}{ 0.08} ]^2 * [0.5 (1- 0.5)]](https://tex.z-dn.net/?f=n%20%20%3D%20%5B%5Cfrac%7B1.96%7D%7B%200.08%7D%20%5D%5E2%20%2A%20%20%5B0.5%20%281-%200.5%29%5D)

I THINK ITS D HAVE A GOOD DAY
Answer: If it has a negative sign then drag it to one that doesn't have one and vice-versa
Step-by-step explanation:
so 0.005 would be -0.005
