The responses showed that 250 households out of 1000 watch movies online, and the interval estimate at 98% was [.20,.30]. If the analyst had used a larger sample size and the same level of confidence, which of the following should have been the new interval? (assume none of the samples were biased)

Question options: [.18,.32] [.22,.28] [.10,.20] [.30,.40]
