The oxidation state of an atom in any pure element, regardless of whether monatomic, diatomic, or polyatomic, is zero. For an explanation of why the sample estimate is normally distributed, study the Central Limit Theorem. The confidence interval depends on the sample size, n (the variance of the sample distribution is inversely proportional to n, meaning that the estimate gets closer to the true proportion as n increases); thus, an acceptable error rate in the estimate can also be set, called the margin of error, , and solved for the sample size required for the chosen confidence interval to be smaller than e; a calculation known as "sample size calculation.". EX: Given that 120 people work at Company Q, 85 of which drink coffee daily, find the 99% confidence interval of the true proportion of people who drink coffee at Company Q on a daily basis. FACIAL.
