Extracted text: 10.23, Certain rockets are manufactured with a range of 2,500 meters. It is theorized that the range will be reduced after the rockets are in storage for some time. Six of these rockets are stored for a certain period of time and then tested. The ranges found in the tests are as follows: 2,490, 2,510, 2,360, 2,410, 2,300, and 2,440. Does the range appear to be shorter after storage? Test at the 1% significance level.
