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 32 beams using the new glue, recording for each beam the pressure (in pounds per square foot) at which the beam breaks. The data collected are presented in the following frequency distribution. Carrying load (in pounds per square foot) Frequency 860 to 879 4 880 to 899 9 900 to 919 12 920 to 939 4 940 to 959 3 Based on the frequency distribution, using the midpoint of each data class, estimate the mean carrying load of the beams tested.
