What is the area under the normal curve between z equals 0 point 0 and z equals 2?
About two. Don't understand why that would be a curve, though. Two points describe a straight line. In that case the answer is exactly two.
-----------------------------
The above is not the correct answer. It's a multiple choice question and 2 is not one of the options. Go to the discussions section to see the answers that are available for me to choose.

The above answer is not correct because of two reasons: one is that it seems to have been answered by a non-statistician. And the second is that normal was not capitalised so that a critical clue was missed. Do you see how important capitalising a single letter can be?
Anyway, the question refers to the Standard Normal or Gaussian distribution, and the area under that curve, between Z = 0 and Z = 2 is 0.4772 ie option D.

Why does the minimum point of avc curve lie to the right of minimum point of mc curve?
AVC=AC-AFC,the AVC curve is simply the vertical difference between the AC and AFC curve, AFC gets less, the gap between AVC andAC narrows.since all marginal costs are variable ,the same relationship holds between MC and AVC as it did between MC and AC ,that is ,when MC is less than AVC ,it must be falling, if MC is greater than AVC .it must be rising, so ,as with the AC curve ,the MC curve crosses the AVC curve at its minimum point
What is the equation of the line tangent to the curve y equals cos x at the point x equals pi over 6?
y = 2(x) - (pi/3) + (sqrt(3)/2)
Parabola is the point at which the parabola is at its lowest or highest point?
A parabola is NOT a point, it is the whole curve.
How do you apply standard deviation to normal curve?
The distance between the middle and the inflection point is the standard deviation.
What point does the normal intersect?
The normal intersects a curve at a right angle, forming a perpendicular line to the tangent of the curve at that point. This intersection is crucial for determining the rate of change or slope of a function at a specific point.
What is the definition of a tangent line?
A tangent is a line that just touches a curve at a single point and its gradient equals the rate of change of the curve at that point.
What point on the normal curve represents the most commonly occurring observation?
The top point
What point on the normal curve represents the most commonly occurring observations?
The top point
What musical object is often used to describe the curve normal distribution produces?
A bell curve describes the graphed curve that normal distribution produces for a set of data. The curve slopes upward before returning downward after the point of the mean.
What is the relationship between the normal boiling point and vapor pressure of a substance?
The normal boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure. In other words, the higher the vapor pressure of a substance, the lower its normal boiling point will be.
What is a line or smooth curve?
Between the two point line to say that is both a curve and there are clear.
What is the value of c when y equals x plus c is a tangent to the curve y equals 3 -x -5x squared hence finding the point of contact of the line with the curve showing work?
-2
What is the equation to the tangent line to the curve xy plus y2 equals 0 at the point x equals 3 and y equals 0?
y=0. note. this is a very strange "curve". If y=0 then any value of x satisfies the equation, leading to a curve straight along the y axis. For any non-zero value of y the curve simplifies to y = -x. The curve is not differentiable at the origin.
What is the value of k when y equals 3x plus 1 is a line tangent to the curve of x squared plus y squared equals k hence finding the point of contact of the line to the curve?
It is (-0.3, 0.1)
