[Phy121s26] Correction to slide 59 of Lecture 1

This morning, during office hours, I discovered a mistake on slide 59 of the slides I used on Tuesday. The equation showing the standard deviation of the weighted average was not squared. I have attached the corrected slide. Thanks to Benjamin for discovering this problem. Frank Wolfs _____________________________________________________________________ Frank L. H.
