59:15 / 1:20:06 I chose C. WRONG. visualise! C part: numerator and denominator trick. Even if there are outliers in A. The cluster could higher in the centre of A. So even though a few divations high, denom VERY HIGH so LOW SD. vala case is possible!
thank you ! if you add a new number within one standard deviation, the SD gets smaller, what if you add a new number that's an outlier or larger than the one SD?
Thankyou. Best teacher I’ve found!
