Please use Rstudio to answer the following. Thank you. Sounds that are either a tone or a monkey call are fed into monkeys through electrodes attached to the brain. Of interest is a response measured by the firing rate (electric spikes per second). It is believed there are more spikes associated with calls than with tones. a. Use a paired test to analyze the data. Summarize results giving test statistics, df, p-value, and state null and alternative hypotheses. Note this...
