Based on the information provided, it seems that the first statement, "Four of Nakeysha’s friends are observed," is likely the true statement. The other options either provide specific assumptions about the behavior of her friends or state an incorrect total number of observations which can’t be verified without the actual dot plot.
Since I don't have visual access to the dot plot, I can't definitively confirm the correct answer. However, if the dot plot confirms that there are indeed four observations, then that would be the correct response.
