Use a proportional confidence interval formula:
CI95 = p + or - (1.96)(√pq/n)
Note: + or - 1.96 represents 95% confidence interval.
For p in your problem: 442/1004
For q: 1 - p
n = 1004
Be sure to convert all fractions to decimals. It's easier to work with decimals in the formula.
I let you take it from here to calculate the interval.
