Usage of "as to whether" [closed]

Can I ask you a question?

People have varied perceptions as to whether parents should arrange the activities that children do in their free time.

Is this sentence grammatically correct? Did the way I use the phrase "as to whether" sound natural to you?

First, using "as to whether or not" instead of "as to whether" (as one contributor recommended) is an example of needless wordiness. It often sounds "better" to use more words, but such redundancy is an affectation and should be avoided. There is no difference in meaning between the two alternatives, and in standard written English it is better to avoid wordiness (see Strunk and White's Elements of Style or George Orwell's "Politics and the English Language" for the philosophy behind advocating economy of style).

The formulation "question(s) as to (+ embedded question)" can be used when the embedded clause is a yes/no question (in which case we would use "whether...") or an interrogative ("as to what/when/where...", etc.). Your formulation is correct and standard.
