Early estimations pegged the mortality rate for corona virus in certain populations as high as 10%.  There are a lot of factors to consider when trying to estimate this particular parameter.  One very important factor to remember is that as test kits become more readily available, we will be testing those who don't have severe symptoms (and thus most likely showing as a case but most likely surviving).  As of the other day, out of 369,000 people who were determined to have the virus, 11,000 died.  Based on that estimation, can we conclude that the absolute mortality rate has decreased? Please calculate the test statistic and pvalue. What can be concluded?  Support your answer. Please calculate the 95% confidence interval Interpret the interval. What can be concluded?  Support your answer.
