Denning [Date] [Course title]
, Evolution - Correct Ans: Change in the frequency of an allele in a population overtime
Gene Pool - Correct Ans: The sum of all alleles in a population
Null Hypothesis - Correct Ans: A statement about the population that either is believed to be true or is
used to put forth an argument unless it can be shown to be incorrect beyond a reasonable doubt
null hypothesis example - Correct Ans: "there is no association between two phenomena"
null hypothesis example - Correct Ans: "there is no linkage between two genes
alternative hypothesis - Correct Ans: a claim about the population that is contradictory to the null
hypothesis and what we can conclude when we reject the null hyp
One-tailed hypothesis - Correct Ans: only one direction of an effect or relationship is predicted in the
alternative hypothesis of the test
one-tailed hypothesis example - Correct Ans: "our company's new drug works better than the
competitor's"
two-tailed hypothesis - Correct Ans: both directions of an effect or relationship are considered in the
alternative hypothesis of the test
two-tailed hypothesis example - Correct Ans: "our company's new drug works differently than the
competitors"
Chi-square test - Correct Ans: sum of (obs-exp)^2/exp
P<0.05 - Correct Ans: reject the null hypothesis
P>0.05 - Correct Ans: fail to reject the null hypothesis
