Compute the standard deviation of both longboards and shortboards.

Longboard: 17, 6, 9, 21, 6, 7, 5, 18, 22, 8, 17, 19, 19, 12, 15, 15, 21, 5, 22, 22, 15, 21, 13, 11, 4, 11, 7, 14, 20, 11 Shortboard: 6, 10, 12, 8, 11, 10, 13, 19, 9, 12, 6, 8, 20, 13, 18, 20, 10, 19, 14, 8, 15, 16, 10, 16, 6, 16, 14, 19, 19, 16b. Compute the standard deviation of both longboards and shortboards. The standard deviation for longboards is days. (Round to one decimal places as needed.)
