Question

Refer to the accompanying table of notebook batteries recorded at four different time intervals on five different days. These values represent the quality control measures used to ensure consistent battery weight.

Table displaying notebook battery weights recorded over five days, including time intervals, mean, and range values.

Compute the average sample mean (x̄̄) and the average range (R̅) using the data above. Find the control limits for the R-chart (LCL_R and UCL_R).

Accepted Answer

x̿ = 12.5

R̅ = 0.05

LCL_R = 0.00

UCL_R = 0.114

Answer

x̿ = 12.5

R̅ = 0.05

LCL_R = 0.05

UCL_R = 0.114

Answer

x̿ = 10.5

R̅ = 0.05

LCL_R = 114

UCL_R = 0.00

Answer

x̿ = 10.5

R̅ = 0.00

LCL_R = 0.01

UCL_R = 1.14
