$\mathrm{HCH}$ Industries has decided to use a p-Chart with 2-sigma control limits to monitor the proportion of defective castings produced by their production process. The quality control manager randomly samples 200 castings at 10 successively selected time periods and counts the number of defective castings in the sample. Table Control Chart Step 8 of 8: You, acting as the quality control manager, have concluded that the process is "Out of Control". What is the probability that the process is really "In Control" and you have made a Type I Error? Round your answer to three decimal places. $\mathrm{HCH}$ Industries has decided to use a p-Chart with 2-sigma control limits to monitor the proportion of defective castings produced by their production process. The quality control manager randomly samples 200 castings at 10 successively selected time periods and counts the number of defective castings in the sample. Table Control Chart Step 6 of 8: At the next time period, 200 castings are sampled and 25 defective castings are detected. $\mathrm{HCH}$ Industries has decided to use a p-Chart with 2-sigma control limits to monitor the proportion of defective castings produced by their production process. The quality control manager randomly samples 200 castings at 10 successively selected time periods and counts the number of defective castings in the sample. Table Control Chart Step 5 of 8: At the next time period, 200 castings are sampled and 10 defective castings are detected. $\mathrm{HCH}$ Industries has decided to use a $p$-Chart with 2-sigma control limits to monitor the proportion of defective castings produced by their production process. The quality control manager randomly samples 200 castings at 10 successively selected time periods and counts the number of defective castings in the sample. Table Control Chart Step 4 of 8: What is the Lower Control Limit? Round your answer to three decimal places. $\mathrm{HCH}$ Industries has decided to use a p-Chart with 2-sigma control limits to monitor the proportion of defective castings produced by their production process. The quality control manager randomly samples 200 castings at 10 successively selected time periods and counts the number of defective castings in the sample. Table Control Chart Step 2 of 8: What value of $z$ should be used to construct the control chart? 3 Hawkes Learning $\mathrm{HCH}$ Industries has decided to use a p-Chart with 2-sigma control limits to monitor the proportion of defective castings produced by their production process.
