comment Two-alternative forced choice
This question will be unanswerable until you explain what "correct" means and how it is related to the other material you introduce.

comment What is the variance of the weighted mixture of two gaussians?
@Neodyme By definition, the variance is the second moment minus the mean squared. Therefore, the second moment is the variance plus the mean squared.

comment How to quantify and test Cricket statistics, the model is number theory based?
If your readers don't recognize your notation or terminology, don't blame them: clarify and explain the notation. Your final sentence is particularly puzzling, because it does not tell us what $n$ might be: it appears to offer infinitely many options.

comment How to create an index of a several variables that best summarizes them?
That's the right word: you're making up the answer. There's nothing wrong with that, as long as (1) you recognize what you're going and (2) you don't claim your invention is the result of some kind of statistical analysis.

comment A statistical interaction is significant, but the author denies it. Why?
@Lauren For counterpoint, consider that this is a post hoc statement. A truly rigorous experimenter would establish criteria both for p-values and effect sizes in advance and respect those criteria in their assessment of the results. If, as implied here, the p-value criterion is 0.05, then this result of 0.048 is significant, period. To state otherwise would be akin to challenging you to a mile-long race, losing, and then at the finish line proposing that the race really was two miles and therefore hasn't been lost.

Do you have a direct measurement of "popularity"?

comment remove the mean over multiple measurements
@gung The problem lies in the question. Questions that ask for the names of things tend not to fit our format well: as linksys says, they really need only a one or two word answer.

comment Critical point for 'hat values' in a normal linear model
Hint: $n$ and $k$ are two numbers and the first two sentences of your question include two numbers. But don't do it! Throwing out such data is exactly the wrong procedure. That's because this criterion identifies the data that potentially have the most impact on the estimates: they're important! Throwing them out would be like benching all your tall basketball players because they are the best scorers on the team.

comment What is $C$ in the four parameter logistic Law?
It doesn't change the shape at all: it merely relabels the values of $x$ on its axis.

comment Should an interpolation coincide the original function on the given data points?
Alas, they are referred to as interpolation. See the literature on time series, spatial analysis, or stochastic processes, inter alia. Some people, but definitely not all, call this "inexact interpolation". One well recognized authority, Noel Cressie, actually equates the words "smoothing" and "interpolation." He sees "smoothing (or interpolation) , filtering, and prediction" as all being the same thing, which he calls "spatial prediction" (Statistics for Spatial Data, 1st Ed., pp 105-6).

comment What is $C$ in the four parameter logistic Law?
Hint: If $x$ were time in minutes and you wished instead to express the law in hours, then evidently $x$ would be replaced by $x/60$. Can you identify $C$ in this expression?

Although you posted an (unintelligible) response from your teacher, you didn't post the original question. What exactly is your question?
