Answer:
a) The required sample size n= 55011,57025
b) The sample size is not practical, because that size is extremely large and would be very costly to collect, normally the size have to be significant but no to large to avoid cost unnecessary
Step-by-step explanation:
Range
⇒ 0,99
Sample size can be determinate using equation:
Using confidence level desired 99% 
= 2,58
Table used :
<em>Confidence 
</em>
<em> 90 % 1,60</em>
<em> 95 % 1,96</em>
<em> </em><em> 99 % 2,58</em>
<em> 99,9 % 3,291</em>
So replacing:
Answer:
Step-by-step explanation:
Note that the sine wave is shifted up by 1/2 and the peak is at 5/2 so subtract the 1/2 from the 5/2 to get the amplitude of this wave.
It's 2
Yes, it does because all of those can be multiplied by 9. So, H*9=P. And It means for every hour of work she gets paid 9 dollars. Or 9 dollars an hour.
Answer is p y = 1200x + 300
The formula for perimeter is 2l+2w. Since we know l=(w-4)-9, we can substitute this into the formula.
l=w-13
2(w-13)+2w=143
2w-26+2w=143
4w=169
w=42.25 units
Hope this helps!
