Answer

Brief Explanations:

A run - on sentence combines two or more independent clauses without proper punctuation or conjunctions. Here, "It is estimated that ten percent of the population has a fear of needles" and "medical researchers are developing devices that make injections pain - free" are two independent clauses joined only by a comma, which is a comma - splice (a type of run - on).

Answer:

yes
