Abstract:
Two new species of Tomocerus (Ocreatomurus) are described from Gyirong Valley, Xizang Autonomous Region, China. Tomocerus (Ocreatomurus) gyirongensis sp. nov. and Tomocerus (Ocreatomurus) oppositus sp. nov. are both similar to Tomocerus (Ocreatomurus) spinulus Chen & Christiansen, 1998 in the absence of blunt dorsal chaetae on manubrium and presence of single large distal dental spines, but these three species can be distinguished mainly by body color, number of tibiotarsal strong inner chaetae, number and position of manubrial prominent chaetae, and arrangement of basal dental spines.

Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
