The five pieces of information provided are insufficient to generate a Meaningful statistic as each represents Data not directly related to each of the others because of time spans represented.(With the exception of#'s 1 and 4 which will give you percentage of Players Immediately active.
Since the broadest time period given is 60 days, to get some ballpark stats i suggest observing, or obtaining the other Four stats,(Hourly observations of Stat # 4 will give you peak player times.) for a period of sixty days.Once you have compiled this information you can then determine;
-average percentage of Total SL resident accounts that are active.
-averaged per capita $L expenitures hourly/Daily/Monthly
-Peak spending days of the week
-peak player days of the week
-peak player times
Those are the ones that come Immediately to mind, but then I never excelled at Mathematics Myself, I'm sure with a Little more work other game conditions can be determined from just these Five.
If you ask LL, I'm sure they can provide just about any Stat you desire based upon the past One, Two, and Three years of records,which they would naturally have kept for their own reference since SL opened.
And remember
"87.236% of all statistics are made up on the spot"
