QUESTION 6 The first fossils of eukaryotic cells appear in the fossil record about two billion years ago four million years ago three billion years ago three million years ago QUESTION 7 The Biological Species Concept described by Ernst Mayr says that a species is individuals that share a similar diet a population or group of populations that can interbreed and produce fertile offspring a population whose members do not compete with each other for resources a group of individuals who have the same phenotype QUESTION 8 The differences between human cytochrome c (a protein) and the same protein in other species are as follows: Rhesus monkey: 1 difference; Pigeon: 12 differences; Fruit fly: 24 differences. What can we infer from this information? that humans and rhesus monkeys have a more recent common ancestor than humans and pigeons. that Rhesus monkeys are more closely related to humans than to pigeons or fruit flies that fruit flies are more distantly related to humans than pigeons all of these answers are correct QUESTION 9 The process by which new species originate is germination is adaptation is speciation occurred for millions of years but is no longer occurring QUESTION 10 Many unrelated species consume the blood of other animals, such as the vampire bat, the vampire finch (a bird) and mosquitos. They have needle-like mouth parts and anti-coagulants in their saliva. The same adaptations across a number of unrelated species is an example of convergent evolution disruptive selection sympatric speciation artificial selection
1. Multiple-choice questions on Advanced Placement exams have five options: A, B, C, D, and E. A random sample of the correct choice on 400 multiple-choice questions on a variety of AP exams shows that B was the most common correct choice, with 90 of 400 questions having B as the answer. Does this provide evidence that B is more likely than 20% to be the correct choice? (e) Calculate the z-test statistic. (f) Use Table A to find a range for the p-value. (g) Using StatKey, find the p-value. (h) State the conclusion of the test in context. (i) Find a 95% confidence interval for the proportion of questions on all AP exams having B as the correct choice using the normal distribution and the formula for standard error. Show your calculations.
