ANOVA is a technique that permits the comparison of the equality of means for multiple populations. Thus, 3 means could be compared and a determination of whether or not one of the means is significantly different from others can be made. This technique is extremely useful, but, as is always the case, the application requires a firm understanding of models assumptions. Consider the following scenario. A meticulously determined random sample of 200 observations is taken from a very large population. This data divides into 4 groups or factor levels, and a numerical measure for each observation is recorded. The population distribution of the measure appears to be slightly skewed positive. The 4 groups have the following number of observations 30, 100, 15 and 55. Which of the following statements leads to the greatest concern in using ANOVA as an analytical technique.
a. Unequal sample sizes among groups can seriously affect the power of the test.
b. Slightly skewed positive distribution of population measures seriously affect the power of the test.
c. In this scenario, I should be concerned about whether the data has been gathered in a biased fashion.
d. Four is not a sufficient number of groups into which to divide the data.

Answers

Answer:

c. In this scenario, I should be concerned about whether the data has been gathered in a biased fashion.

Explanation:

ANOVA is a statistical method which separates observed variance data into different components to use. One way ANOVA is used for three or more groups of data. The greatest concern in ANOVA is that the data gathered should not be biased.

black coffee has a pH of 5, therefore its H+ concentration is ______ times greater than a solution with a pH of 10.

Answers

Answer:

100,000

Explanation:

pH of coffee = 5

pH of solution = 10

Concentration of H+ ions between successive pH values are in multiples of 10

Hence, the pH difference :

pH of solution - pH of coffee

(10 - 5) = 5

Hence, difference in H+ ions will be :

10^5 = 10*10*10*10*10 = 100,000 times

Name three ways that humans benefit from the use of seedless plants

Answers

Answer:

They support life by being the first vegetation to spring up on harsh terrain where soil is scarce. Even when they perish, seedless plants give back to nature. Certain seedless plants like moss and liverworts actually leave behind a layer of fertile soil for other plants when they perish.

Explanation:

Seedless plants have historically played a role in human life through uses as tools, fuel, and medicine. Dried peat moss, Sphagnum, is commonly used as fuel in some parts of Europe and is considered a renewable resource.

A conservation biologist is working to protect elephant seal populations. Elephant have a classic type I survivorship curve with very low levels of juvenile mortality and high survivorship rate. They insist that reducing threats to adults is more important than protective juveniles. Are they correct

Answers

Answer:

Elephants and Classic Type I Survivorship Curve

The conservation biologist is correct.

Explanation:

Classic type 1 survivorship curve means that mortality of elephants increases as they age, and their fecundity (or fertility) decreases as they age.  Therefore, reducing the threats to adults should be more important than protecting the younger elephants.  The younger elephants have higher rates of survival and fecundity than their older parents.

Imprinting can be cell-type specific; for example, this region of chromosome 15 is ONLY imprinted in neurons and a few other specific cell types, but it is not imprinted in most cells in the body, such as bone, liver, and heart cells. Which of the following statements are true about a healthy individual without Prader-Willi or Angelman syndrome? ( Choose two answers)
a. Maternal and paternal copies of SNRPN are expressed at the same level in heart cells.
b. The maternal and paternal copies of UBE3A are differentially expressed in bone cells.
c. The maternal copy of SNRPN has DNA methylation at its promoter in liver cells.
d. Expression of the paternal copy of UBE3A is silenced in neurons.

Answers

Answer:

The correct answer is - A and D.

Explanation:

Genetic imprinting is DNA modifications that result in changing the expression but not the sequence. Factors That affect such changes present both within and outside the cell.

It is a result of the silencing of either maternal or paternal alleles in a pair. This occurs random and leads to phenomenon like X-inactivation. The mechanism involves methylation of the DNA to be silenced. paternal copy of UBE3A is silenced in neurons.
