The аttentiоn spаn оf а twо-year-old is exponentially distributed with a mean of about eight minutes. Suppose we randomly survey 60 two-year-olds. In words, Χ = _______ Χ ~ _____(_____,_____) In words, X = ____________ X ~ _____(_____,_____) Before doing any calculations, which do you think will be higher? Explain why. The probability that an individual attention span is less than ten minutes. The probability that the average attention span for the 60 children is less than ten minutes. Calculate the probabilities in part e. Explain why the distribution for X is not exponential.
