<span>Of SiF4 and SiBr4, the atom SiF4 is more polar. This is because the cation of both molecules are Silicon, but the anions of each are different. In SiF4, the anion is Fluorine, which is more electronegative than the Bromine in SiBr4, which creates a larger dipole, which results in a more polar molecule.</span>
Subjects in the population are sampled by a random process, using either a random number generator or a random number table, so that each person remaining in the population has the same probability of being selected for the sample.
How to Estimate a Population Total from a Simple Random Sample
1. This lesson describes how to estimate a population total, given survey data from a simple random sample. ...
2. Sample mean = x = Σx / n.
3. Population total = t = Nx.
4. where N is the number of observations in the population, and x is the sample mean.
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. ... In this case, the population is all 250 employees, and the sample is random because each employee has an equal chance of being chosen.
Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.
DNA replication follows the base pairing rule (A with T and G with C). This ensures identical replication of the genetic information; hence it's conservation. Each daughter DNA double helix contains one old strand of DNA and one newly-synthesized strand of DNA. This is known as the semi-conservative mechanism.
DNA replication also occurs during mitosis which produces haploid gametes. Each parent contributes half of the genetic information during fertilization of two gametes, thus regenerating the diploid number. Genes from both parents are transmitted to the offspring.
20 calories per ounce.
The average calorie content of human milk is 20 cal/oz.
The calorie content can vary throughout each feeding
and the day, because of the change of fat content. If the breast is empty of milk, this will cause the milk to be high in fat. While if it's empty, the milk will contain less fat.
Covalent bond radius refers to half of the distance between two singly bonded atoms of the same element ( homonuclear X-X bond) and is denoted rcov. In other words, it is defined as half the covalent bond length when the two atoms bonded are homonuclear.
