How To Return Hourly Minimum Count Of Column For A Given Range Of Date

This is the code I have written and I am trying to retrieve minimum count of PQpageId for every hour for a given date of range.

WITH CTE AS (
SELECT PQIM.PQPageID
,PQIM.PageURL as PageDescription
,CONVERT(Date,NCPI.RequestDateTime) AS [Date]
,DATEPART(HOUR,NCPI.RequestDateTIme) AS [HOUR]
,ISNULL (COUNT(NCPI.PQPageID),0)AS HourlyPQPageIdCount
FROM dbo.NewCarPurchaseInquiries AS NCPI WITH (NOLOCK)

[Code] ....

This is the output I get :

PQPageId Date HOUR MINCOUNT
-------- ---------- ---- --------
1 04-11-2015 8 2359
1 05-11-2015 8 2332
1 06-11-2015 8 2008
1 07-11-2015 8 1964
1 08-11-2015 8 2139
1 09-11-2015 8 54

[Code] ....

But I am expecting

PQPageId Date HOUR MINCOUNT
-------- ---------- ---- --------
1 09-11-2015 8 54
1 11-11-2015 9 10
1 11-11-2015 10 4
2 11-11-2015 8 10
2 11-11-2015 9 2
2 11-11-2015 10 1

For ex: Pqpageid 1, at 8am on date 4-11-2015 has a count of 2359 and on 9-11-2015 at 8 am it has count 54then it should return date 9-11-2015 and count 54 for hour 8 like wise for every pageid and hour from 8 to 23 it should return the min count from given date of range.
