Lake Martin and Lake Fields are two large local lakes inhabited by white sturgeons. Some time ago there was an environmental disaster at Lake Martin. Mai is an environmentalist who wants to see if the middleweight (inkg) of the adult white sturgeons now living on Lake Martin is less than median weight (inkg)of the adult white sturgeons now living in Lake Fields. The ecologist captures a random sample ofeleacunt white sturgeons in Lake Martin and a random sample of 12Adult white sturgeons in Lake Fields. (These samples are chosen independently.) The weight of each fish is recorded (inkg). These data are shown in the table. weights (inkg) Lake Martin Sturgeon 77.6, 86.7, 73.0, 79.1, 76.1, 75.8, 74.2, 78.5, 82.5, 75.5, 80.5 Lake Fields Sturgeon 74.1, 96.0, 82.2, 81.7, 87.8, 111.7, 63.6, 70.2, 112.3, 77.8, 104.0, 104.5 Send data to calculator Send data to Excel Assume that the two populations of weights follow approximately a normal distribution.
