Although the answer choices are not complete, we may evaluate the probability of each event.
Total silver medals = 99
Great Britain's silver medals = 17
A should be 17/99
Total Russian medals = 82
Russian bronze medals = 32
B should be 32/82 = 16/41
Total gold medals = 137
Chinese gold medals = 38
C should be 38/137
Total US medals = 104
US silver medals = 29
D should be 29/104
Using the z-distribution, the 95% confidence interval of the population mean is: (17.5, 24.5).
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:

In which:
is the sample mean.
is the standard deviation for the population.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
For this problem, the other parameters are:

Hence the bounds of the interval are:


The interval is: (17.5, 24.5).
