The results of a blinded study assessing the use of plasma
D-dimer levels for diagnosing deep venous thrombosis (DVT) in
patients hospitalized for stroke rehabilitation reported increased
accuracy over the standard procedure involving ultrasound. To test
the claims of this research team, an independent researcher
conducted a study to determine if there was a difference in the
accuracy of diagnosis for DVT between the two methods. The data in
the table below summarize the findings of this study.

in
GIS, we can use cartesian cordinate system, 3 D cordinate system.
how do we fit that 3D system to the actual earth ( mountains,
Vales) then how do we get that back to 2D system screen.
1. What does Levene’s test do? How do we know which line to use
for this test when writing up the results?
2. How can we use confidence intervals to do hypothesis
testing?
How do we know the answer for that? The answer is 6.
You perform a Q-test on a particular data point and obtain a Q
value of 0.67. How many data points would you need to be able to
reasonably discard this data point as erroneous?
How do we determine the test statistic and p-value?
This is a general question, not pertaining to any specific
statistical case. Please provide the equation to calculate the test
statistic and p value.
6.What do we test for in the Voges-Proskauer test?
a. Name a species that will test positive.
7.What are the fermentation products made by bacteria which
carry out mixed acid fermentation?
