Whats wrong with the others? t-Interval for m: with 90.00% Confidence, 38944 6 m1TchPay2 6 42893 a) If we took many random samples of 288 Nevada teachers, about 9 out of 10 of them would produce this confidence interval. b) If we took many random samples of Nevada teachers, about 9 out of 10 of them would produce a confidence interval that contained the mean salary of all Nevada teachers. c) About 9 out of 10 Nevada teachers earn between $38,944 and $42,893. d) About 9 out of 10 of the teachers surveyed earn between $38,944 and $42,893. e) We are 90% confident that the average teacher salary in the United States is between $38,944 and $42,893.

August 21, 2017 and August 23, 2017 The goal of class this week is to model the change in genetics of a population overtime. First, we have some definitions: Genome: bank of genetic information on a specific species Mutation: a change in the DNA sequence which arises in an individual and which MAY spread through the population Polymorphism: a mutation which is found in some (but not all) members of a population Substitution: a change in the DNA sequence which has been fixed in the population Fixation: a new variant in the DNA replaces an old variant Fitness: number of (surviving) offspring produced by an individual compared to the average number of (surviving) offspring produced by the population Genetic Drift: for some reason, alleles are being pulled from a population Gen
