Corporation is contemplating using a new glue in the construction of its laminated veneer lumber. Of importance to the company is the variability of the carrying load of the lumber. The company has tested 40 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 histogram. Frequency 20- 15+ 10+ 5+ 0- 41 860 4 0 16 12 4 900 920 880 Carrying load (in pounds per square foot) 940 4 960 Based on this histogram, estimate the standard deviation of the sample of 40 carrying loads. Carry your intermediate computations to at least four decimal places, and round your answer to at least one decimal place. (If necessary, consult a list of formulas.) Em
