Is the inflection in the sentence normal? To my native-English ears it sounds like a statement rather than a question.
I'm with miguelthebrave. The intonation doesn't sound at all like a question.
Probably because Hebrew doesn't do questions by placing a verb at the beginning of the sentence like English. Yes/no questions are created by changing the tone of the sentence and optionally placing the question word האם at the beginning.
My question was about prosody. Everything else about this sentence seems like a perfectly normal question to me.
