Answer:
The possible values for X is: 
Yes, it is a discrete random variable.
Step-by-step explanation:
Consider the provided information.
We need to determine whether the variable is discrete or not.
Discrete variables are which can only take on a finite number of values.
Let the variable X be the number of unbroken eggs in a randomly chosen standard egg carton.
In a standard egg carton we can put 12 eggs.
Therefore, the possible values for X is: 
The number of unbroken eggs (X) can take infinite values, thus by the above definition it is a discrete random variable.
Answer:
97% confidence interval for the survey is between a lower limit of 0.45 and an upper limit of 0.67
Step-by-step explanation:
Confidence Interval is given by the mean + or - error margin
The lower limit of the confidence interval is found by subtracting the error margin from the mean.
The upper limit is obtained by adding the error margin to the mean.
The interpretation is that the mean is between 0.45 and 0.67
Price after off =80- 1/4 * 80 = 80-20 = $60
Coupon discount = 60*10/100 = $6
So, he have to pay, 60-6 = $54
