2 question to answer plz ???
regarding the first question what I don't understand is why he didn't use ''square root 10'' as a standard variation ??? what's your opinion
astarmathsandphysics:
Your skew diagram is exactly right
astarmathsandphysics:
Normal distribution is written N(mean, standard deviation^2) so standard deviation = sigma=10
As for the second I will post an attachment
