Tests of hypotheses about population proportions. The first number is to be used for the first five sample points; the second number is to be used for the next three sample points; and the third number is to be used for the last two sample points. If the population is normal, the resulting statistic: Tests of hypotheses about population variances.

In a left-tailed test, the p-value is the area to the left of the test statistic if the test statistic is negative. Is there evidence to conclude that the plant in question is violating the law?
