If we want to be 95% confident of our estimate, does the sample proportion obtained, 20 out of 50, fall within the margin of error developed from the simulation? why or why not?

20/50 = 2/5 = 0.40 which is found in the dot plot given. Since this value is in the dot plot, this means that it is possible to obtain this value with a random simulation.

Yes, the sample proportion 20/50 falls within the margin of error.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
