S6B-1. Can someone show me how to do this problem?

Will rate a thumb up for good response thanks so much (PLEASE CIRCLE OR HIGHLIGHT final answer thx)

Refer to Table 56.1 - Factors for Computing Control Chart Limits (3 sigma) for this problem. R= 1.54 lb. Thirty-five samples of size 7 each were taken from a fertilizer-bag-filling machine at Panos Kouvelis Lifelong Lawn Ltd. The results were: Overall mean = 54.75 lb.; Average range a) For the given sample size, the control limits for 3-sigma x chart are: Upper Control Limit (UCL;) = Ib. (round your response to three decimal places). Lower Control Limit (LCLZ) = Ib. (round your response to three decimal places). b) The control limits for the 3-sigma R-chart are: Upper Control Limit (UCLR) = 16. (round your response to three decimal places). Lower Control Limit (LCLR) = Ib. (round your response to three decimal places).
