Blood type and COVID-19 susceptibility - A group of researchers in Wuhan, China investigated the relationship between contracting the novel coronavirus and patients' blood type. The population in Wuhan has a blood type distribution as shown in the table below. The researchers categorized $nsamp patients who had contracted coronavirus by blood type. Round all calculated values in this problem to 4 decimal places. ITT Blood Type Population Percentage COVID-19 patients Туре А 33% 115 Туре В 24% 101 Туре АВ 9% 41 Туре O 34% 118 Total 100% 375 1. Enter the expected values for the hypothesis test in the table below: Blood Type Expected Value Туре А Туре В Type AB Туре О 2. The researchers wonder if, in Wuhan, COVID-19 patients have a different distribution of blood type than the general population of Wuhan. Express this research question in terms of a null and alternative hypothesis. Ho: The distribution of blood type of COVID-19 patients is the same as v the population. Any observed difference is v due to chance. HA: The distribution of blood type of COVID-19 patients is different from v the population. Any observed difference is not due to chance.
