As the sample size increases, the t-distribution becomes more similar to the ________ distribution. a. normal b. binomial c. chi
kvv77 [185]

As the sample size increases, the t-distribution becomes more similar to the <u>normal</u> distribution.

<u>Option:</u> A

<u>Explanation:</u>

Student t-distribution is any member of a group or family of constant probability distributions that emerge in circumstances where the sample size is limited and the standard deviation of the population is unspecified when calculating the mean of a naturally distributed population.

The z-distribution implies you are conscious of the normal population deviation (never in case) when used for sample means. The t-distribution is focused on using the standard sample deviation as an approximation of the standard deviation in population.

Explain the idea of genetic drift. How does natural selection effect genetic drift.
Anettt [7]

Genetic drift is defined as a shift in the allelic frequency of a population. This can be caused by natural selection which is the differential survival and reproduction of individuals across a population due to differences in phenotype. Natural selection favors particular traits in a population hence these individuals are able to reproduce while the individuals with disadvantageous traits will pass their genes to succeeding generations. This way the allelic frequency of succeeding generation will be diferent from that of the parent population.
