Hi, I need help with this question. Please explain in details
how you got the answer with steps shown for each part so I can
understand it thank you.
The mean x and standard deviation s measure center and variability but are not a complete description of a distribution. Data sets with different shapes can have the same mean and standard deviation. (Data set may be found here. Round your answers to two decimal places.) Data A: 9.14 8.14 8.74...

12.35 x and s are not enough. The mean x and standard deviation s mea- sure center and variability but are not a complete description of a distribu- tion. Data sets with different shapes can have the same mean and stan- dard deviation. To demonstrate this fact, use your calculator to find and s for these two small data sets. Then make a stemplot of each and commert on the shape of each distribution. Data A: 9.14 8.14 8.74...
