A 3-sigma control chart is established and the following two rules are used together to detect out-of-control situations of a normally distributed process. Rule 1: 3 out of 4 consecutive points are outside of 1.75 sigma but still within the control limits. Rule 2: One point outside the control limits. Compute the total type 1 error both rules are used together. Select one: a. 0.0038 O b. 0.0044 C. 0.1243 O d. 0.0154 e. 0.0024
