You conduct a study to determine the impact that varying the
amount of noise in an office has on worker productivity (0 – 25).
You obtain the following productivity scores:
Low Noise
Medium Noise
Loud Noise

For each condition, determine the sample mean and the sample
(unbiased) standard deviation. Report the means and standard
deviations in a bar graph (include the whiskers on the bars). Write
an interpretation...
A first year statistics class took part in a simple experiment.
Each person took their pulse rate. They then flipped a coin and, if
it came up tails, they ran in place for one minute. Everyone then
took their pulse a second time. Of the 92 students in the class, 32
ran in place. In repetitions of this experiment, the number that
run in place should have a binomial distribution with n = 92 trials
and probability of success p...
In the second experiment, you perform everything the same way
you did in the first, but this time you replace the air in each
flask with nitrogen gas (N2) which is essentially inert
before you begin. Graph the data, and be sure to display the
equations of the trendlines for each condition. Insert your graph
below the data table and answer the following questions.

This is a two-part discussion topic. In the first part, you will
demonstrate your understanding of one key aspect of perfect
competition. In the second, you will apply your understanding of
perfect competition to the world around you.
1. In a perfectly competitive industry, buyers and sellers are
"price-takers". What exactly does it mean to say that sellers are
price takers? [Hint: Why does a seller not sell at a price
lower than the market-established equilibrium price? Why does a...
If you were conducting the wire and compass experiment (Part A) near the equator instead of Oregon, would it be necessary to use more or less wire current to cause the compass needle to deflect? Hint: Consider both components of Bnet. Explain your reasoning.
IA 2 is a two-part assignment. The first part requires you to
identify, by statute number, and summarize the statute that
prohibits telephone solicitors from blocking or interfering with a
residential telephone subscriber's caller ID function.
The LIGO experiment, which historically detected gravitational
waves for the first time in September 2015, uses a pair of highly
sensitive Michelson interferometers. These have arms that are 4.00
km long and use powerful Nd:Yag lasers with 1064 nm wavelength. The
beams traverse the arms both ways 280 times before recombining,
which effectively lengthens the arm length to 1120 km. The devices
are tuned so that the beams destructively interfere when they
recombine if no gravitational wave is present. (a)...
Part A) Which is NOT an IPO puzzle?
Huge price spikes in the first couple trading days
Underperformance in the long run
Extreme IPO market cycles
Hiring underwriters to do the job
Part B) Which is NOT an SEO
puzzle?
Negative market reaction on average upon SEO announcements
Long-run underperformance
Very costly to hire underwriters
Extreme SEO market cycles
Is there a way to design an experiment to calculate the total
amount of weight or force a material (such as fabrics/toilet paper)
can support before breaking that does not revolve around the usage
of tensile strength test or extremely large masses? Can we design
an experiment that can be small scaled?
1. An experiment is to be conducted to assess effect of
temperature on the
amount of impurities removed by using water samples contaminated
with the
same level of impurity. Six samples are to be tested at each of 5
temperatures
and the amount of impurities removed in each sample recorded.
(a) What is the response variable?
(b) What is the factor of interest?
(c) What are the levels of this factor?
(d) What experimental design is suitable?
(e) Describe how...
