WHAT IS THE MORTALITY RATE, WHAT IT IS THIS 7%?

Researchers believe that the data reported by governments are suspicious, and thus, the reported mortality rate, 7%, does not reflect the truth. In order to estimate the true mortality rate, the researchers collect data that include 1000 COVID19 cases that resulted in either death or not. Analyze the sample data and construct a 99% confidence interval about the true mortality rate and interpret your findings.

Moreover, the income of each patient is provided, a 95% confidence interval for the average (population) income. Interpret your findings, and make sure that you mention which test you use to construct the interval.

PS. YOU CAN USE WHATVER DATA JUS T TO GIVE ME AN EXAMPLE.
