Question
1-according to recent study 20%,women has been a victim of domestic abuse at some point in their lives..suppose we have randomly and independently sampled 25 women and asked whether they have been a victimof domestic abuse at some point in their lives.find the probability that at 2 of the sampled women have been the victim of domestic abuse at some point in their lives.2- The amount of soda a dispensing machine pours into a 12 ounce can of soda follows a normal distribution with a mean of 12.06 ounces and a standard deviation of 0.04 ounce. The company receives complains from consumers who actually measure the amount of soda in the bottles and claim that there was less than the advertised 12 ounces of soda. What proportion of the soda cans contain less thAn the advertised 12 ounces of soda?
3-the amount of corn chips dispensed into a 20 ounce bag by the dispersing machine has been identified as possesing a normal distribution with a mean of 20.5 ounces and a standard deviation of 0.2 ounce. what proportion of the 20ounce bags contain mors than the advetised 20ounces of chips? 1-according to recent study 20%,women has been a victim of domestic abuse at some point in their lives..suppose we have randomly and independently sampled 25 women and asked whether they have been a victimof domestic abuse at some point in their lives.find the probability that at 2 of the sampled women have been the victim of domestic abuse at some point in their lives.

Explanation / Answer
1.X=number of women who have been the victim of domestic abuse at some point in their lives.
X follows binomial distribution with parameters n=25, p=0.20
Find P(X=2)
=25C2*0.20^2*0.80^23
=0.07
2.For X=12, z=(x-mu)/sigma=(12-12.06)/0.04=-1.5
P(X<12)=P(z<-1.5)=0.0668
3.For X=20, z=(20-20.5)/0.2=-2.5
P(X>20)=P(z>-2.5)=1-P(z<-2.5)=1-0.0062=0.9938
