Some statistics students estimated that the amount of change daytime statistics students carry is exponentially distributed with a mean of $0.88. Suppose that we randomly pick 25 daytime statistics students. Find the probability that the average of the 25 students was between $0.79 and $1.00. (Round your answer to four decimal places.)

    The attention span of toddlers when watching a particular TV show is exponentially distributed with a mean of 8 minutes. Suppose X is the random variable equal to the attention span (in minutes) of a randomly chosen toddler while watching the TV show. Suppose a simple random sample of 60 toddlers has their attention span measured while watching the TV show. Use an appropriate version of the CENTRAL LIMIT THEOREM to find the probability (rounded to four decimal places) that...
