A recent journal found that 56.3% of students who lived in coed dormitories consumed alcohol weekly, compared with 23.5% who lived in single-sex dormitories. A random sample of 1,757 students was selected. Complete parts a-d below.

**a.** What is the probability that more than 50% of the students in the sample consume alcohol weekly?  
Probability = [blank] (Round to four decimal places as needed)

**b.** What is the probability that less than 61% of the students in the sample consume alcohol weekly?  
Probability = [blank] (Round to four decimal places as needed)

**c.** What impact would changing the sample size to 100 have on the results in parts (a) and (b)?

**Options:**  
A. The value of the probability decreases. The new value of the probability in part (a) is [blank] and the new value of the probability in part (b) is [blank]. (Round to four decimal places as needed.)  
B. The value of the probability increases. The new value of the probability in part (a) is [blank] and the new value of the probability in part (b) is [blank]. (Round to four decimal places as needed.)  
C. There is no change in the value of the probabilities.

**d.** Identify the symmetric interval that includes 95% of the sample proportions with a sample size of 1,757 if the true population proportion of students in coed dormitories who consume alcohol weekly is 56.3%. [blank] < [blank] (Round to one decimal place as needed. Use ascending order.)
