Nassa obsoleta and Nassa trivittata. One of the variablesthat Dimon considered was the length of the shell. A randomsample of 300 N. trivittata specimens was selected. The averageshell length for the sample was 15.9 mm., with a standarddeviation of 2.89 mm.Find the 90% confidence interval for the average shell length ofall N. trivittata sea snails.What is the standard error used to calculate this interval?
