Researchers use Elisa to test for Lyme disease. Lyme disease infects 0.0009 of the US population each year. The test has a detection rate of 0.98 and a false positive rate of 0.2.
a. What is the probability of a positive test?
b. What is the probability that a person with a positive result actually has Lyme disease?

a
new screening test for Lyme disease is being evaluated. it was
administered to 1,235 people in maine. While 115 people with the
disease tested positive for it another 47 people who do not have
the disease tested positive for Lyme. 721 people who do not have
Lyme tested negative.
1.
calculate specificity
2.
calculate positive predictive value
3.
calculate the negative predictive value
4.
would you recommend this nrw screening test?

An acute viral disease infects a population of chipmunks, and
only those homozygous for allele b are resistant. (Those
individuals heterozygous or homozygous for allele B are
susceptible and suffer 100% mortality).
A. If the initial frequency of allele b=0.2, what is
the frequency (ignoring mutation) one generation after the
introduction of this disease?
B. What is the mechanism of evolutionary change in this
example?

The disease is Lyme Disease
In 4 to 5 paragraphs, answer the questions below, which mirror
the critical elements for Section IV of the final project. They
will help you complete this section of your final project.
IV. Risk: In this section, you will identify
the population at risk, discuss incidence and prevalence, interpret
data, and discuss treatment options that exist for the communicable
disease.
Have you identified the population that is at
risk of developing or contracting the disease,...

Compare and contrast the use of the following methodologies for
diagnosing disease: ELISA, PCR, WESTERN BLOTS, and Fluorescent
antibody techniques.
In your answer discuss the relative sensitivity and specificity
of the assays.
Lastly, when might culturing methods provide useful information
to the doctor or clinician that the other methods do not.

Researchers often use z-tests to compare their samples to known
population norms. The Graded Naming Test (GNT) asks respondents to
name objects in a set of 30 black-and-white drawings. The test
often used to detect brain damage, starts with easy words like
kangaroo and gets progressively more difficult, ending with words
like sextant. The GNT population norm for adults in England is
20.4. Roberts (2003) wondered whether a sample of Canadian adults
had different scores than adults in England. If...

Researchers are interested in the mean age of a certain
population. Let us say that they are asking the following
questions: can we conclude that the mean age of this population is
different from 30 years? If the sample mean of 10 individuals drawn
from that population is 27and the population variance is 20. Make a
confidence interval of the mean
