900 is the population because that is your total pool. The 35 who receive the survey are the sample. See the key words "random sample"

the statistic is the value you get from the results of the survey which is the mean of the satisfaction score.

We don't really have a parameter.. That would be the mean satisfaction score for all 900. However, we could certainly use our statistic to predict a possible parameter.
