This difference is not significant in either data set. The  
differences among all responses is, however.

These differences are highly significant (both data sets).

In both data sets, the middle-aged (40-49) groups are significantly  
over represented. About a third of all respondents fall into this age  
range. If this indicates an increase in existential concerns in this  
age group, then targeting marketing toward this group could yield  
savings.

A random sample would benefit any marketing effort directed to the  
general public.

The distribution is sig.

These differences are highly significant.

Sig.


A failure to comment doesn't mean a result is significant or non- 
significant.
