Identify the assumption(s) made when computing the 95% confidence interval for the proportion and conducting th hypothesis test. The upstream fish species counts have a normal distribution in the population. The sampling units, or tributaries, are randomly sampled from the population. The paired differences in fish species counts have a normal distribution in the population. The downstream fish species counts have a normal distribution in the population.

Transcribed Image Text:Researchers studying the number of electric fish species living in various parts of the Amazon basin were interested in
whether the presence of tributaries affected the local number of electric fish species in the main rivers (Fernandes et al.
2004). They counted the number of electric fish species above and below the entrance point of a major tributary at 12
different river locations. The results are listed in the table.
