If the proportion of the population in City A that is over 65 years old is p1 and the proportion of the population in City B that is over 65 years old is p2, what is the null hypothesis for a test to determine if the proportion of the population that is over 65 years old is greater in City A?
Expert Solution

A null hypothesis is a statement about an unknown parameter that is framed either from existing beliefs or past experiences. Suppose p1 is the proportion of the population in City A that is over 65 years old and p2 is the proportion of the population in City B that is over 65 years old.
