Suppose second team of researchers in 2009 believed that the rate of encounters in which the whale comes within 3,281 feet of the bow in the lower bay sub-region of Glacier Bay was higher than 20%. This team observed a sample of 85 encounters between cruise ships and whales in the lower bay; the whale came within 3,281 feet of the bow in 25 of these encounters. p = 0.20, find the value of the mean of the sampling distribution of for samples of size 85. Hint: Thanks to the Central Limit Theorem there is no math needed to answer this question. The central limit theorem states that if n is "big enough" then the center (mean) of the sampling distribution for will be equal to the actual, true population proportion
