question 62

Multiple Choice

A proofreader checked 160 ads for grammatical errors. The distribution obtained is shown: $$\begin{array} { | l | c | c | c | c | } \hline \text { Number of Errors } & 0 & 1 & 2 & 3 \\\hline \text { Observed Frequency } & 10 & 65 & 71 & 14 \\\hline\end{array}$$ At ? = .01, what decision would we reach in a goodness-of-fit test to see whether this sample came from a uniform distribution?

• A)Reject the null and conclude the distribution is not uniform.
• B)Conclude that there is insufficient evidence to reject the null.
• C)No conclusion can be made due to small expected frequencies.
• D)No conclusion can be made due to inadequate sample size.

Definitions:

Recessive Allele

Recessive allele refers to an allele that produces its characteristic phenotype only when it is paired with an identical allele (that is, in homozygous states).

Frequency-Dependent Selection

A form of natural selection where the fitness of a phenotype depends on its frequency relative to other phenotypes in the population.

Clone Genotypes

Replicating the genetic makeup of an organism to create a genetic duplicate, leading to individuals with identical genotypes.

Heterozygote Advantage

Occurs when selection favors heterozygote individuals over either the dominant homozygote or the recessive homozygote.
