A biologist captures birds using a series of mist nets placed throughout a private reserve. They place 15 nets into 3 different areas: Orchard, Forest, and Grazing Land. For 3 months, the biologist records the number of birds that were caught in the net and whether or not they were migrating. Following the field season, the biologist begins analyzing the data in R. They want to see if there are any significant differences in the number of migrant birds caught between the 3 areas.(a) What type of variable is the number of migrant birds (continuous/categorical)?(b) What type of variable is area type (continuous/categorical)? (c) What statistical test would you use to analyze this type of data? State your null and alternative hypotheses.
