Aim of the applet

It shows a normal distribution from the average and the standard deviation.

Input data

• Average and standard deviation In the corresponding sliders, with the mouse the values are chosen, and in the forms.
• Delimitadores of calculation of the probability: In the graph there move the points of blue color by means of the mouse.
• "Adjust view" button.
• Generate a random normal and that you manage to obtain µ and σ of it.

Output data

Applet will show the normal distribution with the indicated parameters, marking the region that covers the asked probability and his value.

The first steps

• Represents the normal N (-2.3). By the sliders changes the values of average and standard deviation by observing the behavior of the graph.
• Statures of a population of boys follows the distribution N (170,6). Calculate the probability P (165 < x < 180).
• Generate a random normal and try to change µ and σ until the two functions of the graph overlap.
