Analyze the data in the table by calculating descriptive statistics for the USA gold medal count. We will use these statistics to estimate the expected number of gold medals for the United States in the 2018 Winter Games. Note that the number of events is not the same for every year. Therefore, it will be necessary to take into account the number of gold medals as a percentage of the number of events.

Begin by calculating the number of gold medals won each year as a percentage of the number of events. To do this, divide the number of gold medals by the number of events, and then multiply by $100$. Round your answers to the nearest whole percentage. Create a table similar to the one above with the percentage of gold medals won in each year.

Calculate the range of the number of gold medals and the range of the percentage of gold medals.

Calculate the median number of gold medals and the median percentage of gold medals.

Calculate the mode of the number of gold medals and the mode of the percentage of gold medals.

Calculate the mean number of gold medals won.

Calculate the mean percentage of gold medals won by adding to get the total number of gold medals won in all years, dividing by the total number of events in all years and then multiplying by $100$. Round your answer to the nearest whole percentage. (Note that you cannot average percentages. This is why we have to go back to the numbers of gold medals and the numbers of events.)

Calculate the fivenumber summary for the number of gold medals won.

Draw a box plot for the number of gold medals won.

Using a value of $102$ events in the 2018 Olympics, estimate the expected number of gold medals by multiplying $102$ by the median percentage of gold medals won by the United States.

The United States actually won $9$ gold medals in the 2018 Winter Games in Pyeongchang, South Korea. How does your calculation for the expected number of gold medals compare to the actual number?
