My question asks to construct a 95% confidence interval estimate (rounded to one decimal digit) of the percentage of all employees who would like to work at the office. (1,003 employees, 37.2% want office, critical value of 1.96)

my answer is The 95% confidence interval is between 0.3420872117 to 0.4019127883

Would I round the number after converting into percentage so the answer would be 34.3% and 40.2% or round the actual confidence interval so the answer would be CI = [0.3, 0.4]?
