Can you explain how im suppose solve problem 2 A-C Problem 2: According to the Public Policy Institute of California, 39% of state residents areLatino, 37% are white, 15% are Asian American, 6% are African American, 3% other. Medicalresearchers are wondering whether the Covid-19 infected rate is proportional to the proportionof the population. They randomly select a day in January and count the number of cases. Thetable below displays the breakdown of the cases by race.LatinoWhiteAsian American African American OtherTotal180481502664822853120343612a) If the infected rate is proportional to the population, then how many cases do you expect tosee for each race? Show your work.b) Do we have some evidence to suggest that Covid-19 infected rate is disproportionately highfor some race? Explain. Is this statistically significant?c) Find the Critical x? value for this problem. Use alpha value = 0.05 and df = 4 (because 5categories minus 1).
