Keep in mind that sometimes you have flexibility in which system of nomenclature you use, but sometimes it is dictated to you, for example in publications or other formal submissions. Scientists call an organism that has two different alleles for a trait a. In general, whenever we add two vectors, we add their corresponding components: This works in any number of dimensions, not just three. No; the original population is normally distributed, so the sample means will be normally distributed for any sample size. There are lots of ways to write vectors.

Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? Annual incomes are known to have a distribution that is skewed to the right instead of being normally distributed. Instead of using 0.05 for identifying significant values, use the criteria that a value x is significantly high if P(x or greater)less than or equals0.01 and a value is significantly low if P(x or less)less than or equals0.01.
