Hi there,
If the mean is 7, standard deviation is 2, and sample point is 11, then z-score is 2.
From this, we also know being at least 2 standard deviations from the mean is 0.977, from the pnorm(2) command which equals to 0.977 in the R program calculation.
Question on the pnorm() command in R...
pnorm() has actually 3 or 4 arguments. And the 2 in the pnorm() command above is the z socre, which is not listed as an argument type in the program.
Can you explain why the command works, and also clarify how it works in this case?
