Laser scanning for fish volume estimation. engineers design tanks for rearing commercial fish to minimize both the use of natural resources (water) and the rearing volume necessary to ensure fish welfare.
one key to a well-designed tank is obtaining a reliable estimate of the volume (biomass) of fish reared in the tank.
the feasibility of a laser scanning technique for estimating fish biomass was investigated in the journal of aquacultural engineering (nov.2012). fifty turbot fish were reared in a tank for experimental purposes.
a laser scan was executed in four randomly selected locations in the tank and the volume (in kilograms) of fish layer at each location was measured.
the four laser scans yielded a mean volume of 240 kg with a standard deviation of 15 kg. from this information, estimate the true mean volume of fish layer in the tank with 99% confidence. interpret the result, practically.
what assumption about the data is necessary for the inference derived from the analysis to be valid?

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
