How to get number of clicks, impressions that I would get for my Ad Group Budget ?

[Dawud Dustin]

I need to know whether can I get number of clicks, and impressions that I would receive for a specific budget using Google Ad Word API. Here I am using PHP library. 

For example, if I choose a budget of $50 for an Ad Group, I need to get estimate number of clicks, and impressions that I would get for the budget of $50.

I go through with code - Get keyword traffic estimates as shown  in following link and tried it.

https://developers.google.com/adwords/api/docs/samples/php/optimization#estimate-keyword-traffic 

And it gives me following result. I have set Maximum CPC as 2000000

Results for the keyword with text 'land for sale' and match type 'BROAD':

Estimated average CPC: 355840.00
Estimated ad position: 5.81
Estimated daily clicks: 141.94
Estimated daily cost: 10281407.00
Estimated daily Impressions: 619775235.00

so I want to know how much this is correct with what I am accepting.
