A study of 11 patients is performed to see if there is correlation between age and length of stay in a hospital for a certain infectious disease. Patient 1 is 24 years old, patient 2 is 30 years old, and continuing in order of patient number, 34, 50, 53, 59, 66, 69, 75, 84, 88 years old. Patient 1 stayed in the hospital 7 days, patient 2 stayed 8 days, and, continuing in order of patient number, 10, 6, 14, 9, 11, 15, 9, 23, 19 days.
a) Find the appropriate linear regression equation that would describe a linear relation between the variable of age (make age x) and the length of stay, y.
b) Find the linear correlation coefficient.
c) based on the answer to part b, is there a correlation between age and length of stay?

What is the real difference between between correlation and
regression analysis? I see that correlation allows us to examine
whether two variables exhibit some kind of association with each
other. Does correlation mean means that one variable is dependent
on another? Is this an example of correlation - Tips are dependent
on the actual restaurant bill? Can you give other examples of
correlation and regression?
Thanks.

A researcher performed a retrospective study of the records of
patients receiving care for hypercholesterolemia. The data gives
measurements of total cholesterol for patients before and 6 weeks
after taking a statin drug. Is there sufficient evidence at the
α=.05 level significance to conclude that on an average the drug
would result in reduction in total cholesterol in
hypercholesterolemia patients. Assume total cholesterol in
hypercholesterolemia patients is normally distributed

You are conducting a study to see if the proportion of men over
the age of 50 who regularly have their prostate examined is
significantly less than 0.32. A random sample of 715 men over the
age of 50 found that 196 have their prostate regularly examined. Do
the sample data provide convincing evidence to support the claim?
Test the relevant hypotheses using a 10% level of significance.

A study was performed among patients with progressive chronic
kidney disease to assess the optimal time for the initiation of
dialysis (Cooper et al. [22]). Patients were randomized to
either
an early start group, where dialysis was
initiated when their estimated glomerular filtration rate (GFR) was
between 10.0 and 15.0 mL per minute per 1.73 m2 of body surface
area or
a late start group, where dialysis was
initiated when their GFR was 5.0 to 7.0 mL per minute per...

Now let’s see what is implied by the study of Wuhan patients
that the WSJ article describes. Here’s another quote:
“A February study of about 1,000 patients in Wuhan, China, who
were hospitalized with suspected coronavirus there, where the
pandemic began, found that about 60% tested positive using lab
tests similar to those available in the U.S. But, almost 90% showed
tell-tale signs of the virus in CT scans of their chests, the
article, published in the journal Radiology, found,...

X-axis: 13, 14, 16, 17, 21, 25, 30, 37, 50, 62 (age)
Y-axis: 2, 7, 30, 26, 15, 33, 7, 3, 14, 1 (Makeup sales)
