Hi.

I need to show that the average density of the standard regular distribution is as below in the 0.5 intervals from –4 to 4, but these numbers are not available, so I have a problem.

Which part should I correct to get that number?

The number I need to prove : 0.000 0.002 0.010 0.033 0.088 0.184 0.300 0.383 0.383 0.300 0.184 0.088 0.033 0.010 0.002 0.000

The code that I made

x_dnorm <- seq (-4, 4, 0.5)

y_dnorm <- dnorm(x_dnorm)

round(y_dnorm,3)

Then I get 0.000 0.001 0.004 0.018 0.054 0.130 0.242 0.352 0.399 0.352 0.242 0.130

0.054 0.018 0.004 0.001 0.000

I cannot find where is the wrong point

please help me
