Blood type and COVID-19 susceptibility Agroup or researchers in Wuhan, China Investigated the relationship between contracting the novel coronavirus and patients blood type. The population in wunan has a blood type distribution als shown in the table below. The researchers categorized Snsamp patients who had contracted coronavirus by blood type. Round all calculated values in this problem to 4 decimal places. Blood Type Population Percentage COVID-19 patients Type A 33% 115 Type B 24% 101 Type AB 9% 41 Type o 34% 118 Total 100% 375 1. Enter the expected values for the hypothesis test in the table below: Blood Type Expected Value Type A 123.75 Type B 90 Type AB 33.75 Type o 127.5 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 the population. Any observed difference is due to chance. HA The distribution of blood type of COVID-19 patients is different from the population. Any observed difference is not due to chance. 3. Did blood type A or blood type o contribute more to the test statistic? A. type o ОВ. type A 4. Calculate the test statistic. 5. State the degrees of freedom for this test. df = 3 6. Calculate the p-value for this test. P= 7. Based on the above p-value, we have little evidence against the null hypothesis.
