Which statement below is incorrect
the mean is not affected by the existence of an outler
(b) the median is not affected by the existence of an outlet
(c) the standard deviation
affected by the existence of an outler

The Answer is A

Step-by-step explanation:

The mean or average is highly sensitive to outliers - and is one reason why the median is a more reliable statistic.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
