Amber and Shinji both play a single-player game where they try to survive as many rounds as possible without crashing a bird into an obstacle. Here's the historical data for how many rounds each player survives in a single attempt at this game: Player Shape Mean Std. dev. Amber Normal \[35.5\] \[7.1\] Shinji Normal \[30.0\] \[8.6\] They decide to each play \[10\] attempts and calculate the sample mean of how many rounds they survive. They will then look at the difference in their sample means \[\left( \bar{x}_\text{A} - \bar{x}_\text{S} \right)\]. What are the mean and standard deviation (in rounds) of the sampling distribution of \[\bar{x}_\text{A}-\bar{x}_\text{S}\]?
