Goodness-of-Fit Test · Exercise 17

The cumulative number of COVID-19 related cases reported for Santa Clara County for a certain time period is broken down by ethnicity as in.


The percentage of each ethnic group in Santa Clara County is as in.
\begin{array}{|c|c|c|}\hline \text{Ethnicity} & \text{Percentage of total county population} & \text{Number expected (round to two decimal places)} \\ \hline \text{White} & \text{42.9%} & \text{1748.18} \\ \hline \text{Hispanic/Latino} & \text{26.7%} & \\ \hline \text{Black/African-American} & \text{2.6%} & \\ \hline \text{Asian, Pacific Islander} & \text{27.8%} & \\ \hline & \text{Total = 100%} & \\ \hline\end{array}

Does it appear that the pattern of COVID-19 cases in Santa Clara County corresponds to the distribution of ethnic groups in this county? Why or why not?
