Over the 200,000 years or so that modern humans have existed, human populations have adapted to a wide range of environments, including different foods. The researchers hypothesized that increased consumption of starch-rich foods during human evolutionary history gave individuals with multiple copies of the salivary amylase gene an "advantage." To test their hypothesis, Perry and colleagues analyzed DNA collected from two groups. The first group consisted of populations that have historically consumed a diet low in starch. The other group traditionally ate high-starch foods. The researchers measured the number of copies of the AMY1 gene in individuals from these different populations. The descriptive statistics can be found below. Sample Mean Sample Standard Deviation Sample Size Group |High-Starch Diet 7.12 Low-Starch Diet 5.48 2.92 25 2.18 25 Assuming both groups come from normal populations, what is the 95% confidence interval on the mean difference between the groups (high – low)? O 0.2116 to 3.0684 None of these. 0.1746 to 3.1054

One variety of corn is genetically modified to produce chemicals for defense against predators. The standard corn contains the same standard genotype, but without genetic modification for the chemicals. The two types of corn are then planted in randomly placed adjacent plots across a single field. The amount of predators that are present when the corn has matured are then recorded. The data that was recorded of the predators present among each type are listed. Has genetic alterations decreased the amount of predators for the altered genotype? Normality tests for the populations of both contain a p value less than 0.05. The given alpha is 0.05 Modified Corn (20, 18, 26, 23, 17, 23, 22) Standard Corn (89, 64, 102, 96, 56, 77, 84, 59) use an F test to determine if the variance between the 2 lists are different. Based on this result, state the correct 2 sample parametric test to be used. State the null and alternative. Show calculations while rounding to two decimal points.What is the…
Researchers measured the distribution of beak sizes in a cohort of medium ground finch hatchlings in the Galapagos Islands in 1976 just before, and in a cohort of hatchlings two years after a severe drought. They measured 100 finches in each cohort. After the drought, the proportion of large, harder seeds was substantially greater than before the drought. Their data documenting this selective event are shown in graphical and tabular form below.

A fungal meningitis outbreak has been traced back to a particular compound pharmacy selling a specific injectable drug that is suspected to have been contaminated. In the past 4 weeks 15,051 patients were given the medication, and of those patients 72 individuals contracted fungal meningitis. What is the cumulative incidence for meningitis among those individuals who the medication was administered to?
Cheek teeth of extinct primates. The characteristics of cheek teeth (e.g., molars) can provide anthropologists with information on the dietary habits of extinct mammals. The cheek teeth of an extinct primate species were the subject of research reported in the American Journal of Physical Anthropology (Vol. 142, 2010). A total of 18 cheek teeth extracted from skulls discovered in western Wyoming were analyzed. Researchers recorded the dentary depth of molars (in millimeters) for a sample of 18 cheek teeth extracted from skulls. These depth measurements are listed in the accompanying table. Anthropologists know that the mean dentary depth of molars in an extinct primate species— called Species A—is 15 millimeters. Is there evidence to indicate that the sample of 18 cheek teeth come from some other extinct primate species (i.e., some species other than Species A)? The data are given below (you will need to put it into a single column). You will need to calculate the sample…
Every society has its own marks of wealth and prestige. In ancient China, it appears that owning pigs was such a mark. Evidence comes from examining burial sites. The skulls of sacrificed pigs tend to appear along with expensive orna-ments, which suggests that the pigs, like the ornaments, signal the wealth and prestige of the person buried. A study of burials from around 3500 B.c. concluded that "there are striking differences in grave goods between burials with pig skulls and burials without them . ... A test indicates that the two samples of total artifacts are statistically significantly different at the 0.01 level." Explain clearly why "statistically significantly different at the 0.01 level" gives good reason to think that there really is a systematic difference between burials that contain pig skulls and those that lack them.

Fingerprint analysis and blood grouping are features that do not change through the lifetime of an individual. Fingerprint features appear early in the development of a fetus, and blood types are determined by genetics. Therefore, each is considered an effective tool for identification of individuals. These characteristics are also of interest in the discipline of biological anthropology—a scientific discipline concerned with the biological and behavioral aspects of human beings. The relationship between these characteristics was the subject of a study conducted by biological anthropologists with a simple random sample of male students from a certain region with a large student population. Fingerprint patterns are generally classified as loops, whorls, and arches. The four principal blood types are designated as A, B, AB, and O. The table shows the distribution of fingerprint patterns and blood types for the sample. Expected counts are listed in parentheses. The anthropologists…
A random selection of volunteers at a research institute have been exposed to a typical cold virus. After they started to have cold symptoms, 10 of them were given multivitamin tablets formulated to fight cold symptoms. The remaining 10 volunteers were given placebo tablets. For each individual, the length of time taken to recover from the cold is recorded. At the end of the experiment the following data are obtained.
