1) According to a recent study, 1 in every 10 women has been a victim of domestic abuse at some point in her life. Suppose we have randomly and independently sampled twenty-five women and asked each whether she has been a victim of domestic abuse at some point in her life. Find the probability that more than 22 of the women sampled have not been the victim of domestic abuse. (Hint: Does this satisfy the assumptions of a Binomial experiment? Use the Complerment Rule to find the probability.)N=25 ; p=.10 findP(x>=23)= 1-P(x<23)= 1-1=0 2) A physical fitness association is including the mile run
