Janine works as palliative care nurse at a regional health
facility and relates the following conundrum. Janine describes
looking after Jack who recently returned to the palliative care
service after a further unexpected exacerbation of his respiratory
lung cancer. Jack is rapidly deteriorating with little tolerance
for any activity and cannot undertake any activities of daily
living. Shirley, his wife is constantly at his side offering as
much support as possible. Jack is highly dependent and has several
HCP ‘s...
Work these in R.
Using library(resampledata) and the dataset Spruce to conduct a
test to see if the mean difference in how much the seedling grew
(in height) over the course of the study under these two treatments
are significantly different from each other. Answer the
following:
a) Set up a hypothesis using appropriate notation.
b)Find the value of the observed test statistic using R.
c)Compute the P-value of the observed test statistic using a
permutation distribution with N= 10^5-1....
Business Case
Your company needs to conduct an analysis of a large dataset
that is 10 times bigger than the size of a hard drive of your most
powerful computer. This dataset contains data about ATM
transactions. The security team has provided a smaller dataset of
suspicious transactions. Your task is to identify transactions
similar to suspicious ones.
Directions
explain which parallel computing techniques would be
appropriate for this case and why. Explain which component of
Hadoop ecosystem may be...
Solve using R.
You will need library(resampledata) and the dataset FlightDelays.
Conduct a hypothesis test to see whether there is a difference in
the variances of flight delay length between the two
airlines.
1) Set a hypothesis for this test using appropriate notation
2) Using R, find the value of the observed test statistic
3) Using R, compute the P-value of the observed test statistic
using a permutation distribution with N=10^5-1 resamples.
If possible use comments so that it is...
For each of these problems, conduct a significance
test. Remember there are four steps after
confirming the conditions are met for inference:
1) state the hypotheses
2) calculate test statistic
3) find P-value. Remember that we are using α = 0.05 as our
guideline for statistical
significance. If P-value ≤ 0.05, reject Ho. If P-value > 0.05,
do not reject Ho.
4) state the conclusion in plain English in the context of the
problem, not just “reject Ho” or “do...
Conduct a hypothesis test. Perform each of the following
steps:
a) state the hypothesis and identify the claim
b) Find the critical value(s)
c) Compute the test value
d) make the decision
e) Summarize the results
It has been found that the average time users spend online per
week is 18.3 hours. A random sample of 48 teenagers indicated that
their mean amount of Internet time per week was 19.5 hours with a
population standard deviation of 5.7. At the...
Describe how to conduct a peripheral vascular exam. What is an
Allen test and why would conduct one. What are Arterial Brachial
Indexes, why would you conduct one and what results are considered
normal, and what do abnormal results indicate.
Conduct a hypothesis test for each problem, using the
traditional method. Show the 5 steps and all work for each
hypothesis test. Be sure you select the correct test to use for
each problem.
2. A college statistics instructor claims that the mean
age of college statistics students is 25. A random sample of 98
college statistics students revealed a mean age of 23.1. The
population standard deviation is known to be 3.21 years. Test his
claim at the 0.05...
