Juan repeats the measurement four times and recoeds the mean $\stackrel{}{x}$ of his four measurements.

QWhat is the standard deviation of Juas's meas resulr? $($That is$,$ if han kyst on maling four measurements and averaging them. what would be the standard deviation of all his $\frac{?}{\text{b}\text{a}\text{r}}\frac{x_1}{b}ar(Y_1))$
