    Solve the following problem:

    In the 2010 U.S. Census, the ages of individuals in a small town were found to be the following:

    <18 18-35 >35

    in 2010, ages of n=500 individuals from the same small town were sample. Below are the results:

    <18 18-35 >35

    121 288 91

    Using alpha=.05, would you conclude that the population distribution of ages has changed in those 10 years?
