Explanation:
The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal. Mild, sub-clinical signs of central nervous system toxicity can be seen in workers exposed to an elemental mercury level in the air of 20 μg/m3 or more for several years.
It is important so that some people be ethnic so that those cultures and beliefs do not die off but it is also important for people to evolve as well which is why it is important for some to not be ethnic.
According to the result of the test statistic, the p-values are given by:
a) 0.0352.
b) 0.9648.
c) 0.0704.
<h3>How to find the p-value of a test?</h3>
It depends on the test statistic z, as follows.
- For a left-tailed test, it is the area under the normal curve to the left of z, which is the <u>p-value of z</u>.
- For a right-tailed test, it is the area under the normal curve to the right of z, which is <u>1 subtracted by the p-value of z.</u>
- For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is <u>2 multiplied by 1 subtracted by the p-value of z.</u>
In this problem, the test statistic is z = 1.8, which has a p-value of 0.9648.
Item a:
Right-tailed test, hence the p-value is of 1 - 0.9648 = 0.0352.
Item b:
Left-tailed test, hence the p-value is of 0.9648.
Item c:
Two-tailed test, hence the p-value is of 2 x (1 - 0.9648) = 2 x 0.0352 = 0.0704.
