However, the dosimeter is actually worn by the worker to determine the personal noise dose during the workshift or sampling period (Figure 21). Noise dosimetry is a form of personal sampling, averaging noise exposure over time and reporting results such as a TWA exposure or a percentage of the PEL.
Answer: 0.0241
Step-by-step explanation:
The formula we use to find the margin of error :
, where z* = Critical value , n= Sample size and p = Sample proportion.
As per given , we have
n= 2400
Sample proportion of subjects showed improvement from the treatment:
Critical value for 99% confidence = z*= 2.576 (By z-table)
Now , the margin of error for the 99% confidence interval used to estimate the population proportion. :
[Round to the four decimal places]
Hence, the margin of error for the 99% confidence interval used to estimate the population proportion. =0.0241
Answer:
y4z
Step-by-step explanation:
Answer:
No, they aren't.
Step-by-step explanation:
They are not all collinear points. Collinear points are points lying in a row or on a straight line. However in this figure G and C lie on the same line and are collinear but Y doesn't lie on the line, but elsewhere on the plane. So, we can say they are non- collinear.
Hope this helps!
