Question

The KMn04 test shows that we have a molecule conatining an alkene in our final product. That does not mean that the prouct is necessarily pure. Propose one way our final product could actually be a mixture yet still show a positive result in the KMn04 test.

2. Suppose next that we have even less knowledge of our patient,
and we are only given the accuracy of the blood test and prevalence
of the disease in our population. We are told that the blood test
is 9# percent reliable, this means that the test will yield an
accurate positive result in 9#% of the cases where the disease is
actually present. Gestational diabetes affects #+1 percent of the
population in our patient’s age group, and that...

2. Suppose next that we have even less knowledge of our patient,
and we are only given the accuracy of the blood test and prevalence
of the disease in our population. We are told that the blood test
is 95 percent reliable, this means that the test will yield an
accurate positive result in 95% of the cases where the disease is
actually present. Gestational diabetes affects 6% of the population
in our patient’s age group, and that our test...

Suppose next that we have even less knowledge of our patient,
and we are only given the accuracy of the blood test and prevalence
of the disease in our population. We are told that the blood test
is 96 percent reliable, this means that the test will yield an
accurate positive result in 96% of the cases where the disease is
actually present. Gestational diabetes affects 7 percent of the
population in our patient’s age group, and that our test...

We have manufactured a product and are testing whether it is
better than a competitor's product. We find that 13 of 20 people
prefer our product to the competitor's product. Do we have enough
evidence to declare that we have a superior product, or is there
still doubt?
a. our P-value is above 10%, so there is still doubt
b. out P-value is between 5% and 10%, so there is still
doubt
c. our P-value is below 5% so we...

Hello I have a question about organic chemistry 1 lab.
When doing chemical tests the Br2 in CCl4. Shows a positive
result for alkenes and alkynes? And negative test results mean a
alkene and/or arene? I’m told in lab that we do not have potassium
permanganate so we cannot use it. The second test that were told to
preform if nothing else is shown on the IR is a halide test.
I hope this makes sense. I’m just confused about...

Suppose a test for cancer is given. If a person has cancer, the
test will detect it in 96% of the cases; if the person does not
have cancer, the test will show a positive result 1% of the time.
If we assume that 12% of the population taking the test actually
has cancer, what is the probability (rounded to the nearest
percent) that a person taking the test and obtaining a positive
actually has cancer?

Report how much glucose was present before we started
fermentation (this is 800 mg/dL for everybody because we just did
one representative test). Use this number to calculate the maximum
theoretical mass (in grams) of ethanol that we could have produced
in the fermentation. In other words, given that one molecule of
glucose produces two molecules of ethanol, calculate how many grams
of ethanol could be produced if every single glucose molecule was
converted into two ethanol molecules (this is...

1. ‘We
have to get this new product and fast’, said
the Operations Director. ‘Our
competitors are
close behind
us and I believe their products will be almost as good as ours when
they launch
them’.
She
was talking about a new product that the company hoped would
establish them as
the
leader in the market. The company had put together a special
development team together
with
their own development laboratory. They had spent £10,000 on
equipping the laboratory
and...

test for a certain disease is found to be 95% accurate, meaning
that it will correctly diagnose the disease in 95 out of 100 people
who have the ailment. The test is also 95% accurate for a negative
result, meaning that it will correctly exclude the disease in 95
out of 100 people who do not have the ailment. For a certain
segment of the population, the incidence of the disease is 4%.
(1) If a person tests positive, find...

"To diagnose colorectal cancer, the hemoccult test is
conducted to detect occult
blood in the stool. For symptom-free people over 50 years old who
participate in
screening using the hemoccult test, the following information is
available.
The probability that one of these people has colorectal cancer is
0.3 percent. If a
person has colorectal cancer, the probability is 50 percent that he
will have a
positive hemoccult test. If a person does not have colorectal
cancer, the
probability is 3...
