The average number of mosquitoes in a stagnant pond is 80 per square meter with a standard deviation of 12. If 36 square meters
svp [43]

Answer:

a) 18.4%

Step-by-step explanation:

Assuming a normal distribution, the z-score (z) for the probability of the average of the mosquitoes count being 'X'  is given by:

z(X)=\frac{X-\mu }{\frac{\sigma}{\sqrt{n}}}

Where 'μ' is the distribution mean, 'σ' is the standard deviation and 'n' is the number of square meters chosen.

For X = 81.8 and n=36:

z(X)=\frac{81.8 - 80}{\frac{12}{\sqrt{36}}}\\z(X)= 0.9

A z-score of 0.9 is equivalent to the 81.59 th percentile in a normal distribution.

Therefore, the probability (P) that the average of those counts is more than 81.8 mosquitoes per square meter is:

P= 100\% - 81.59\%\\P=18.41\%
