How does r squared related to standard deviation? Socratic

The Z-score is found by assuming that the null hypothesis is true, subtracting the assumed mean, and dividing by the theoretical standard deviation. Once the Z-score is found the probability that the value could be less the Z-score is found using the pnorm command.
