Briаn Heаd Ski Resоrt hаs a new quad (4 persоn) chairlift. A study оf skiers shows the average weight among all skiers is 125 lbs, with a standard deviation of 30 lbs. Using the Central Limit Theorem, find the following probabilities for the mean weight of a randomly selected group of 4 skiers. What is the probability that the mean weight among a group of 4 skiers is less than 150 lbs? [p1] What is the probability that the mean weight among a group of 4 skiers is more than 130 lbs? [p2] Would it be unusual to find a mean weight of more than 130 lbs among 4 randomly selected skiers? (yes or no) [yesno] What is is the probability that the mean weight among a group of 4 skiers is between 120 and 130 lbs? [p3] Note: round all probabilities to 3 decimal places

In some circumstances, selection will maintain rather than remove variation. F. When the fitness of a phenotype depends on its frequency within the population, it is called selection. G. Rare phenotypes are favored by selection in selection. H. Common phenotypes are favored in selection. I. Sometimes, selection occurs where one phenotype is favored at one time and another phenotype is favored at another time. J. In , selection will favor individuals with copies of both alleles rather than two copies of the same allele.
