Question

The days taken recovery in COVID patients is as following,

a) In BC the mean is 14 days with in a sample of 40 patients and population standard deviation of 1.2.

b) In Ontario, the mean is 16 days in a sample pf 42 patients and population std of 1.

Test hypothesis that mean of these samples are significantly different using critical value approach and alpa = 0.05 show all steps.

(hint z0.05/2 = 1.96)

Answer #1

the days taken in recovery in COVID patients is as follows
in BC the mean is 14 days in a sample of 40 patients, and
population standard deviation of 1.2
in ONTARIO,the mean is 16 days in a sample of 42 patients and
population standard deviation of 1
Test the the hypothesis that mean of these samples are
significantly different using critical value approach
a = 0.05
show all steps

From a previous report, the mean number of days for patients
waiting for bypass surgery is 18.2 days with a standard deviation
of approximately 10 days. The population distribution is skewed
right (positively skewed).
a) If we drew a random sample of 22 patients waiting for bypass
surgery, then would it be reasonable to say that the sampling
distribution of a sample mean, , will be approximately normal?
Answer either yes or no.
b) A random sample of 50 patients...

a random sample of 45 days taken at a large hospital shows that
a mean of 37 patients were treated in the emergency room (ER) per
day. The standard deviation of the population is 4. Find the 95%
confidence interval of the mean number of ER patients treated each
day at the hospital. Express your answers as decimals to the
nearest hundredth , please show work and formulas used to solve
this , thanks so much!

Several years ago, a group of Honda Dealerships determined that
the average amount of days automobiles stay on dealers' lots was
equal to 22.1 days. They now believe that the mean time has changed
and would like to test their belief at a significance level of
0.05. Results of a sample of 50 cars on various lots can be found
in the file Honda Hypothesis Test. Use this information to answer
the next several questions and ultimately decide whether or...

The manager of a grocery store has taken a random sample of 100
customers. The average length of time it took the customers in the
sample to check out was 3.1 minutes. The population standard
deviation is known at 0.5 minutes. We want to test to determine
whether or not the mean waiting time of all customers is
significantly different than 3 minutes. Use α = 0.05.
14. The test statistic is
a. 1.96
b. 1.64
c. 2.00
d. 0.056...

, "Opening up" is thought to improve individuals' mood following
a tragic incident. A health psychologist is interested in its
effect on HIV positive patients. The psychologist collected a
sample of 17 HIV positive patients and asked them to talk about
their HIV related issues ("open up") with their family. The
psychologist assessed the patients' level of hopefulness afterwards
and obtained a mean of 114.58 with a standard deviation of 4.92.
The average hopefulness of HIV positive individuals is known...

Findings In a cohort of 2215 adults
with COVID-19 who were admitted to intensive care units at 65
sites, 784 (35.4%) died within 28 days, with wide variation among
hospitals. Factors associated with death included older age, male
sex, morbid obesity, coronary artery disease, cancer, acute organ
dysfunction, and admission to a hospital with fewer intensive care
unit beds.
Meaning This study identified
demographic, clinical, and hospital-level factors associated with
death in critically ill patients with COVID-19 that may be used to...
