Reyesburg Corporation is contemplating using a new, more expensive glue in the construction of its laminated veneer lumber. Of importance to the company is the carrying load of the lumber. The company has tested 25 beams using the new glue, recording for each beam the pressure (in pounds per square foot) at which the beam broke. The data collected are presented in the following histogram:
