24. The accompanying data set consists of observations on shear strength (lb) of ultrasonic spot welds made on a certain type of alclad sheet. Construct a relative frequency histogram based on ten equal-width classes with boundaries 4000, 4200, . . . . [The histogram will agree with the one in

“Comparison of Properties of Joints Prepared by Ultrasonic Welding and Other Means” (J. of Aircraft, 1983: 552–556).]
