- Please don’t rejectIn constructing a control chart for the proportions of defective coins, a researcher calculates LCL to be 0.000025. What does "LCL" represent, and how should that value be adjusted? www Choose the correct answer below. OA. "LCL" represents the lower control limit. Since - 0.000025 is less than 0.05, this is an unusual LCL and the researcher should adjust the LCL to a value of - 1. OB. "LCL" represents the lower control limit. Since -0.000025 is less than 0 and proportions can never be less than zero, the researcher should adjust the LCL to a value of 0. OC. "LCL" represents the least common logarithm. Since - 0.000025 is less than 0.05, this is an unusual LCL and the researcher should adjust the LCL to a value of - 1. OD. "LCL" represents the least common logarithm. Since - 0.000025 is less than 0 and it is not possible to take the logarithm of a negative number, the researcher should adjust the LCL to a value of 0.25
