Answer:
(B) (0.396, 1.712)
Step-by-step explanation:
From the information given;
Confidence Interval = 0.95
Significance Level 
The confidence interval for regression coefficient beta (whereby in this case it is the coefficient of the diameter) is expressed by:
= 
From the regression coefficient, the estimated value of beta^ = 1.054


To solve this answer, you are trying to find 55% of 600, because that is the number of people who chose plastic bag.
55% can be re-written as 55/100 OR 0.55 since percentages are always out of 100.
So, we do 0.55*600, which gives us 330. 330 people carry plastic bags.
