Overall I'd say this would get a 4 - 4.5 (but other experts, give your own thoughts, I'm not great at gauging essay scores).
The writing itself is good. Meaning, there are few grammatical mistakes, your thoughts are organized, etc.
The main thing to look at here is the 'Critical Reasoning' aspect of the essay (Essays are basically assumption family CR questions).
For specific points:
I hoped to see a very explicit: "It's possible that both the increase in art program viewers and the increase in art museum attendance are caused by a third factor, and not that the art programs are causing museum attendance," and/or "It's possible that attending the museum drove interest in art that caused the increase in TV viewers of art programs." You seem to imply there might be one cause increasing viewers and another cause increasing museum attendance, and definitely suggest that the increase in museum attendance might be caused by something other than the TV programs, but never quite mention that a common cause might lead to increases in both program viewers and museum attendance.
You write "Moreover, it is mentioned that television is the medium where most visual arts appear but it does not clarify if the increasing number of television viewers is in fact from the number watching visual arts specifically"
But the prompt doesn't mention generic increase in television viewers. It specifies an increase in viewers of programs about visual arts. It says most of these programs are on public television, so it would be a good point to ask if most viewers are watching *those specific programs*, or if, maybe, there is a very popular program that almost everyone watches that is not on public television, but it seems you've interpreted the prompt to mean 'television viewing is up 15%, and there are art programs on public television.'
The point about 'recent, but how recent' seems a little soft.
I also don't quite follow this point:
"Another fact that needs to be investigated is the comparison of percentage of population- depicted in the results of the survey as well as the museum crowd. The population today could be much more than it was five years ago and consequently 15 percent five years ago could be much lesser than 15 percent today"
The passage doesn't mention '15% of the entire population.' It says that the number of people viewing art shows and the number attending art museums have both increased by ~15%.
I think it would be a very solid point to ask about population growth. If the total population has grown by 15%, well... it makes sense that these groups also grew by 15%. I think you were going for this idea, but I can't quite see it in a the comparison of '15% of the population 5 years ago' and '15% of the population today.'
In an essay, you want to find ASSUMPTIONS, possible STRENGTHENERS, and possible WEAKENERS. Some examples are below (a * means you mention it)
ASSUMPTIONS:
--The survey is accurate and unbiased, and responders were honest (you dance around this with the 'recent but how recent' point).
--The cause of museum attendance is not something besides the TV programs*
--Going to the museum isn't what caused people to watch more art programs.
--The increases in viewers of art programs and in museum attendance do not correspond closely to an increase in population (you dance around this one)
--The TV programs that people are watching are the programs on public television
--The cuts to public television will result in fewer programs/viewers of programs about the arts
STRENGTHENERS:
--Anything to verify the survey results (you dance around this with the 'recent but how recent' point).
--Anything that indicates new museum attendees are new viewers of art programs, and even better, that the new museum attendees are there because they saw the TV programs.
--A population growth in the city of <15%
--Data that shows the viewers watch art programs on public TV and not on other channels.
--Information that the art programs will be among the cuts.
WEAKENERS:
--The art in the museum is completely different from the art in the programs*
--The survey in either year was biased or misleading (you dance around this with the 'recent but how recent' point, though I just don't think that's the tack to take for this argument).
--Anything that could cause both increases (e.g. an expansion of art programs in schools).
--Anything that shows museum attendees aren't viewers of the shows, or aren't there because of the shows.
--Data that shows art programs on non-public TV get a majority of the views.
--That the art programs won't get cut.
--A population growth in the city of 15% or more (again, you dance around this one).
There are other points to be made, but these are some that jumped out to me. You mention a few, tiptoe close to others. But some you overlook, and some of the points you do make seem to imply a misinterpretation of the argument in the prompt. The writing is strong, and the thoughts are organized. Hence, a 4-4.5.
Since the biggest issue here was the 'CR' aspect of the essay, here are a few videos that might help:

The first thing to do in the essay is to really map out the arguments logic:
PREMISES:
--15% increase in viewers of art programs on TV. Similar increase in art museum attendance.
--Many art programs are on public TV
--Corporate funding for public TV about to get slashed.
CONCLUSION 1: We can expect a decrease in art museum attendance.
CONCLUSION 2: We should allocate funds that support the arts to public TV, which will keep art museum attendance up.)
