We are 95% confident that the variance is between 916.6 and 2252.1.

The round-off rule says that we should round the boundaries of the interval by one more decimal place than the sample values. Then the interval becomes: $\sigma^2 $ is between 916.6 and 2252.1. We are 95% confident that the variance is between 916.6 and 2252.1.
