The resistance of each resistor in a packet of 15 resistors with a nominal value of 560 U was measured, and the following values in ohms were recorded: 546 558 585, 539, 542, 570, 566, 541, 563, 574,...

The resistance of each resistor in a packet of 15 resistors with a nominal value of

560 U was measured, and the following values in ohms were recorded:

546 558 585, 539, 542, 570, 566, 541, 563, 574, 547, 568, 550, 534, 572

Calculate the mean value, median value, standard deviation, and standard error of the

mean for the set of resistance values.
