JNU SSS 2016 Question 4: Random variables and standard distributions

Suppose an unbiased coin is tossed repeatedly 25 times under the same conditions.

If the unbiased coin was replaced with a coin biased towards the outcome head, the standard deviation of the number of tails in 25 tosses (compared to that for the unbiased coin) would have been
