5.38 Tomato as a taste modifier. Miraculin-a protein naturallyproduced in a rare tropical fruit-can convert a sour tasteinto a sweet taste; thus, it has the potential to be an alterna-tive low-calorie sweetener. In Plant Science (May 2010), agroup of Japanese environmental scientists investigated theability of a hybrid tomato plant to produce miraculin. For aparticular generation of the tomato plant, the amount x ofmiraculin produced (measured in micrograms per gram offresh weight) had a mean of 105.3 and a standard deviationof 8.0. Assume that x is normally distributed.a. Find P(x > 120).b. Find P(100 < x < 110).c. Find the value a for which P(x < a) = .25.

Step 1:To solve the problems based on the normal distribution, we need to use the standard normal…

The recessive mutation bg (beige) in mice results in a decrease in the activity of natural killer cells in homozygous mutant mice. You test the hypothesis that this cell type plays an important role in rejection of tumor cells (derived from a tumor induced in an isogenic animal) by injecting animals with genotypes bg/bg or bg/+ with 106 cells and measuring the time required for the development of a palpable tumor in each animal. You obtain the following data: Time to tumor development (days) Genotype 28, 51, 47, 80 14, 35, 17, 37, 16 3. What is the most appropriate statistical approach to test the hypothesis? a. t-test for paired samples b. t-test for unpaired samples C. ANOVA d. Mann-Whitney U test e. Kruskal-Wallis test 4. Is there a significant difference in tumor latency between the two groups? bg/+ bg/bg
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.

PTC is a substance that has a strong bitter taste for some people and is tasteless for others. The ability to taste PTC is inherited and depends on a single gene that codes for a taste receptor on the tongue. Interestingly, although the PTC molecule is not found in nature, the ability to taste it correlates strongly with the ability to taste other naturally occurring bitter substances, many of which are toxins. About 75%75% of Italians can taste PTC. You want to estimate the proportion of Americans with at least one Italian grandparent who can taste PTC. (a) Starting with the 75%75% estimate for Italians, how large a sample must you collect in order to estimate the proportion of PTC tasters within ±0.1±0.1 with 90%90% confidence?

Bisphenol A in Your Soup CansBisphenol A (BPA) is in the lining of most canned goods, and recent studies have shown a positive association between BPA exposure and behavior and health problems. How much does canned soup consumption increase urinary BPA concentration? That was the question addressed in a recent study1 in which consumption of canned soup over five days was associated with a more than 1000% increase in urinary BPA. In the study, 75 participants ate either canned soup or fresh soup for lunch for five days. On the fifth day, urinary BPA levels were measured. After a two-day break, the participants switched groups and repeated the process. The difference in BPA levels between the two treatments was measured for each participant. The study reports that a 95% confidence interval for the difference in means (canned minus fresh) is 19.6 to 25.5 μg/L. (a) Is this a randomized comparative experiment or a matched pairs experiment?

One of the issues facing organizations is increasing diversity throughout an organization. One of the ways to evaluate an organi- zation's success at increasing diversity is to compare the percentage of employees in the organization in a particular position with a specific background to the percentage in a particular position with that specific background in the general workforce. Recently, a large academic medical center determined that 9 of 17 employees in a particular position were female, whereas 55% of the employees for this position in the general workforce were female. At the 0.05 level of significance, is there evidence that the proportion of females in this position at this medical center is different from would be expected in the general workforce?
The mango is considered the "king of fruits" in many parts of the world. Mangoes are generally harvested at the mature green stage and ripen up during the marketing process of transport, storage, and so on. During this process, about 30% of the fruit is wasted. Because of this, the impact of harvest stage and storage conditions on the postharvest quality are of interest. In this experiment, the fruit was harvested at 80, 95, or 110 days after the fruit setting (the transition from flower to fruit) and then stored at temperatures of 20∘C, 30∘C, or 40∘C. For each harvest time and storage temperature, a random sample of mangoes was selected, and the time to ripening was measured. What are the factors, the treatments, and the response variables? Take each item from the answer bank and place into the appropriate category.

11.82 Researchers measured the specific activity of the enzyme sucrase extracted from portions of the intestines of 24 patients who underwent an intestinal bypass. After the sections were extracted, they were homogenized and analyzed for enzyme activity (Carter, 1981). Two different methods can be used to measure the activity of sucrase: the homogenate method and the pellet method. Data for the 24 patients are shown here for the two methods: Sucrase Activity as Measured by the Homogenate andPellet MethodsPatient Homogenate Method, y Pellet Method, x1 18.88 70.002 7 .26 55.433 6.50 18.874 9.83 40.415 46.05 57 .436 20.10 31.147 35.78 70.108 59.42 137 .569 58.43 221.2010 62.32 276.43 11 88.53 316.0012 19.50 75.5613 60.78 277 .3014 77 .92 331.5015 51.29 133.7416 77 .91 221.5017 36.65 132.9318 31.17 85.3819 66.09 142.3420 115.15 294.6321 95.88 262.5222 64.61 183.5623 37 .71 86.1224 100.82 226.55a.

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 AMY 1 gene in individuals from these different populations. The descriptive statistics can be found below. Group High-Starch Diet 7.12 Low-Starch Diet 5.48 Sample Mean Sample Standard Deviation Sample Size 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)?…
