Select the best process listed below for each of the following statements. Note that you need to know that the sequence of amino acids directly reflects the sequence of genes that coded for their placement.
-A small region of a protein from three species is sequenced and found to be as follows:
Species X is alanine, glycine, glycine, threonine, alanine
Species Y is alanine, glycine, threonine, alanine
Species Z is alanine, glycine, glycine, threonine, alanine
The difference in the amino acid sequence of species Y is most likely due to this.
Type II Error
A Type II Error occurs when a statistical test fails to reject a false null hypothesis, falsely indicating no effect or difference when one exists.
Level of Significance
The probability threshold below which the null hypothesis is rejected in hypothesis testing.
Probability
A mathematical measurement of the likelihood of an event occurring, expressed as a number between 0 and 1.
Level of Significance
The criterion used for rejecting the null hypothesis; often denoted by alpha.
