Question

If age and sense of humor are not correlated then Question 29 options: 1) a third variable causes both age and sense of humor 2) old people have good (high) senses of humor 3) old people have poor (low) senses of humor 4) old people have no senses of humor 5) some old people have good senses of humor and some don't

Answer 1

5) some old people have good senses of humor and some don't

If two variables are not correlated, it can be random. Which means, there is no proper relation to be found between the two variables. Here, two variables are age and sense of humor. When there are not correlated, there is no connection between the two. So, it doesn't matter what age a person is of with regards to that person's sense of humor. Any person of any age can or cannot have sense of humor.
