The two-way table shows the medal count for the top-performing countries in the 2012 Summer Olympics.
Yanka [14]
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

A random sample of n D 225 and xN D 21 was drawn from a normal population with a known
Rainbow [258]

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:

\overline{x} \pm z\frac{\sigma}{\sqrt{n}}

In which:

  • \overline{x} is the sample mean.
  • z is the critical value.
  • n is the sample size.
  • \sigma is the standard deviation for the population.

In this problem, we have a 95% confidence level, hence\alpha = 0.95, z is the value of Z that has a p-value of \frac{1+0.95}{2} = 0.975, so the critical value is z = 1.96.

For this problem, the other parameters are:

\overline{x} = 21, \sigma = 26.8, n = 225

Hence the bounds of the interval are:

\overline{x} - z\frac{\sigma}{\sqrt{n}} = 21 - 1.96\frac{26.8}{\sqrt{225}} = 17.5

\overline{x} + z\frac{\sigma}{\sqrt{n}} = 21 + 1.96\frac{26.8}{\sqrt{225}} = 24.5

The interval is: (17.5, 24.5).
