Thank you so much, at least i got that part right. But what is the meaning of the e-11 at the end?? Thanks again You commands are correct and the interpretation is that the probability that a normal random variable with mean 1454.190 and standard deviation 162.6301 achieves a value of 417 or le

Hi, i am trying to determine a certain probability and i am unsure if the commands i have entered into R are correct. I am trying to determine how unusual it would be to find something with the value 417 for a set of numbers with mean 1454.190 and standard deviation 162.6301. The command i entere
