Samples:

A) The bass in Clear Lake have weights that are normally distributed with a mean of2.3pounds and a standard deviation of0.6pounds.

What percentage of all randomly caught groups of 3 bass should weigh between2.1and2.5pounds?Enter your answer as a percentage rounded to one decimal place._________

B) Assume the average life-span of those born in the U.S. is78.2years with a standard deviation of16years. The distribution is not normal (it is skewed left). The good people atLive-Longer-USA(fictitious) claim that their regiment of acorns and exercise results in longer life. So far,35people on this program have died and the mean age-of-death was83.7years.

Calculate the probability that a random sample of35people from the general population would have a mean age-of-death greater than83.7years.Round your answer to 4 decimal places._________
