3) The researchers have a few research questions they want to consider. Determine which distribution / test would be the most appropriate to use for the researcher's key questions. Note: So far in this class, we have considered the following distributions Binomial , Chi2, z (standard normal), t, and anova. a. Did the homicide rate in 2010 equal the homicide rate in 2020? Or was the homicide rate significantly different? b. 32% of the cities experienced 0 homicides in 2020. If we then take 5 New Jersey cities at random, what is the probability that all 5 of those cities experienced a homicide? c. Is the 2020 homicide rate different across the 4 regions studied? d. Is the homicide rate different across cities which are majority Hispanic (more than 50%) compared to cities that have fewer than half of their residents identifying as Hispanic
