I$\text{'}$m happy to help! However, I$\text{'}$m a text$-$based AI and cannot actually insert a spreadsheet into this chat. But I can provide you with a sample spreadsheet format that you can use to organize your data and calculations:$*$Range and Mean Calculations$*|$ City $|$ House $1$ Price $|$ House $2$ Price $|$ House $3$ Price $|$ House $4$ Price $|$ Mean $|$ Range $||---|---|---|---|---|---|---||$ City $1|250000|270000|290000|260000|265000|40000||$ City $2|230000|240000|220000|250000|235000|20000||...|...|...|...|...|...|...||$ City $10|280000|300000|290000|310000|295000|30000|*$Control Limits$*||$ UCL $|$ LCL $||---|---|---||$ Range $|60000|0||$ Mean $|282000|248000|*$Conclusion$*-$ The range of prices is in control for the state since all ranges fall within the UCL and LCL limits$.-$ The mean of prices is in control for the state since all means fall within the UCL and LCL limits$.$You can use this format to insert your data and calculations, and then attach the spreadsheet to your post. Let me know if you have any further questions or need any additional assistance!
