Step-by-step explanation:
Answer:
a

b

Step-by-step explanation:
Considering question a
From the question we are told that
The mean is 
The standard deviation is 
The standard error of mean is mathematically represented as

=>
=> 
Generally the probability that the mean volume of a random sample of 144 bottles is less than 12 oz is mathematically represented as


From the z table the area under the normal curve to the left corresponding to -0.3425 is

=>

Generally the probability that the mean volume of a random sample of 144 bottles is less than 12 oz is mathematically represented as


From the z table the area under the normal curve to the left corresponding to -1.0274 is

=> 
The answer should be half (Can be written as .5 or 1/2) because there are only two types of twins, fraternal and identical. So therefore the probability is half
