Answer:
The sample required is
Step-by-step explanation:
From the question we are told that
The standard deviation is
The margin of error is
Given that the confidence level is 99% then the level of significance is mathematically evaluated as
Next we will obtain the critical value from the normal distribution table(reference math dot armstrong dot edu) , the value is
The sample size is mathematically represented as
substituting values
Hey there! :D
We will use the properties of similar triangles to figure this out.
We will use two triangles inside the kite, with sides with the value of "x".
Smaller triangle:
Smaller side= 11
Bottom side= x
Bigger triangle:
Smaller side= x
Bottom side= 25
Cross multiply.
25*11= 275
x*x=
Find the square root.
√275= 16.583....
Or 5√11.
I hope this helps!
