How would you define the sampling universe and why you chose this sample definition?
The sampling universe is the totatility of items/events from which you can select or sample for statistical analysis and description.
What does the central limit theorem say about the shape of the sampling distribution of?
The central limit theorem can be used to determine the shape of a sampling distribution in which of the following scenarios?
What is the difference between a probability distribution and sampling distribution?
A sampling distribution function is a probability distribution function. Wikipedia gives this definition: In statistics, a sampling distribution is the probability distribution, under repeated sampling of the population, of a given statistic (a numerical quantity calculated from the data values in a sample). I would add that the sampling distribution is the theoretical pdf that would ultimately result under infinite repeated sampling. A sample is a limited set of values drawn from a population. Suppose I take 5 numbers from a population whose values are described by a pdf, and calculate their average (mean value). Now if I did this many times (let's say a million times, close enough to infinity) , I would have a relative frequency plot of the mean value which will be very close to the theoretical sampling pdf.
Are ecologist and environmentalist the same?
Broadly speaking yes. The difference would be that generally we would say that the ecologist has a career and the environmentalist supports a movement.

Is it better to be an actress or an ecologist?
Well, being an actress would be great.. Great pay (; But, you might not always get the chance to become a big actress like Jennifer Aniston or someone like that. So, I say ecologist, If you have the shot to become an actress, go for it, but keep that ecologist job in your mind :D P.S. If you become famous you better talk to me >:)

When is census necessary instead of sampling?
census is conducted for group data so if it is a sampling data is taken it would lead to lot of non sampling errors
What type of scientist studies biotic factors?
I would describe such a scientist as an environmental scientist.
Which of the following levels of organization would and ecologist be most interested in studying?
cell
Why the random sample is important in design of experiment?
There are circumstances when it is important and others when it is not. If, for example, you wanted a sample of all schools in the country, it would make more sense to go for cluster sampling. A lot of market research work will require quota sampling. So the supremacy of a random sample is a myth.
Where would be the earth 3 months later after it's lined up with the sun?
The question doesn't make much sense. The Earth is always"lined up" with the Sun, in the sense that you can always draw a line through two points.The question doesn't make much sense.
