A research team wanted to compare the difference between serum
uric acid levels in patients with and without Down syndrome. A
sample of 12 individuals with Down syndrome yielded a mean of 4.5
mg/100 ml with standard deviation 1 mg/100 ml while a sample of 15
individuals without Down syndrome yielded a mean of 3.4 mg/100 ml
with standard deviation 1.2 mg/100 ml. Let those with Down syndrome
be group 1 and those without be group 2. Note: When doing
calculations with the means and standard deviations, just use the
main number. For example: “4.5 mg/100 ml” –> just use 4.5

Place Order

A. What are the sample statistics (p̂1 and
2 or ȳ1 and ȳ2)? Please
calculate/write their values and calculate their difference
(p̂1-p̂2 or ȳ12).

B. Construct a 95% confidence interval for the
true average difference in serum uric acid levels overall between
those with Down syndrome and those without. Use t* = 2.06 if
solving by hand. Provide the interval in (left endpoint, right
endpoint) format.

C. Interpret the confidence interval in the context of the
study.
