To calculate the control limits for the 11eabc4c_bb11_4909_8797_c931917f14e4_TB2972_11-chart, we need to use the formula:
LCL = 11eabc4c_bb11_701a_8797_7f96e1259362_TB2972_11 - (3/√n)
UCL = 11eabc4c_bb11_701a_8797_7f96e1259362_TB2972_11 + (3/√n)
Substituting the given values, we get:
LCL = 0.45 - (3/√15) = 0.446
UCL = 0.45 + (3/√15) = 0.454
Therefore, the answer is C.
