1. It is thought that all Homo sapiens originated from a breeding population of __________________ individuals.
a. 600
b. 2000
c. 5000
d. 10000
2. What is the "pit of bones" in Northern Spain?
a. Where 30 complete skeletons of H. heidelbergensis were found.
b. A 50' vertical shaft.
c. A primitive burial site.
d. All of the above.
3. Teeth can tell us how fast Neanderthal children were growing.
True
False
4. Humans take _____________ as chimpanzees to reach adulthood.
the same amount of time
twice as long as
three-times as long
5. Homo neanderthalensis brains were larger than Homo sapien brains. Because of this, Neanderthal mothers must have been relatively old when they gave birth, so that they could support infants with such big, fast-growing (metabolically-demanding) brains.
True or False

Problem Statement
You have the mRNA sequence that results from the transcription
of the Homo sapiens Hemoglobin subunit beta gene. Knowing that the
5' and 3' ends of the mRNA are processed post-transcriptionally,
you know that the start codon and termination codon lie somewhere
inside the sequence. A manual inspection of the mRNA sequence
should reveal the locations of the start and stop codons, but to
ensure you don't miss anything you decide to write a Python script
to analyze...

Individuals from two separate true-breeding strains of white
deer mice are crossed yielding all grey offspring. White is
recessive to gray color based on crossing mice from each strain
with a grey mouse. Which of the following would best explain this
result?
a. lethal alleles
b. multiple alleles
c. epistasis
d. complementation
e. incomplete dominance

True/False:
1. If you ask a population ecologist, all the individuals in a
population belong to the same species.
2. A single population might exist in multiple territories
that do not overlap, with no migration of individuals between
territories.,
3. A population's carrying capacity depends on the action of
parasites.
4. Most populations have a random dispersion pattern.
5. In general, animals are most likely to die at an age near
their maximum possible lifespan.

A mouse from a true-breeding population with normal gait was
crossed to a mouse displaying an odd gait called “dancing.” The F1
animals all showed normal gait. If dancing is caused by
homozygosity for the recessive allele of a single gene, what
proportion of the F2 mice should be dancers if you cross two F1
mice?
25%
50%
75%
0%
33%

A researcher samples 15 individuals from a population of
butterflies and measures their body mass at pupation, and wants to
compare the sample to a previously-reported mean of 1.2g using a
one-sample t-test. The sample mean is 0.97g with a standard error
of 0.14. What is the value of the t-statistic?
Select one:
a. -1.643
b. 1.643
c. 0.123
d. 0.231

In the Brazilian population the share of individuals
with blood from the O + group is 36% and O- is 4%.
Let X be the number of people with blood type O, in a
random sample of 800 Brazilian citizens.
Determine the narrowest interval of type A = [a, b],
such that P {X€A}> 0.95.
B. In a random sample of 100 Brazilians, what is the
probability that exactly 30 of them
are from group O? and 2 of group...

A sample of 16 individuals is selected from a population with μ
= 75. A treatment is administered to the sample. After treatment, M
= 82 and s2 = 64.
1. Find the 90% confidence interval.
2. Find the 95% confidence interval.
3. What happens to the width of the interval when you increase
the level of confidence (the percent confidence)?
4. Does the confidence interval always include the population
mean, sample mean, or both?

A sample of n = 16 individuals is selected from a population
with µ = 30. After a treatment is administered to the individuals,
the sample mean is found to be M = 33. A. Assume that the sample
variance is s2 = 16. Compute a single sample t-test to evaluate if
the treatment produced a significant effect and calculate r2 to
measure the size of the treatment effect. Use a two-tailed test
with α = .05. B. Now, assume...

A sample of n = 16 individuals is selected from a population
with µ = 30. After a treatment is administered to the individuals,
the sample mean is found to be M = 33. a. If the sample variance is
s2 = 16, then calculate the estimated standard error and determine
whether the sample is sufficient to conclude that the treatment has
a significant effect? Use a two-tailed test with α = .05. b. If the
sample variance is s2...
