If the lowest score of a set of data is shifted lower, the mean score will not change. True False

False.

Explanation:

The mean score is the average, therefore if one piece of data is changed, it will alter the average score. The median is not affected by changing the lowest score as it does not affect the order of the scores.

hello!

according to the passage the most suitable options are two. the first one is "by leading the aef to victory in several key battles" like the battle of saint- mihiel and the battle of cantigny mentioned in the passage you copied here. the second one is "by the aef and allied forces defeat germany" since the passage says that his army destroy the german resistance in the meuse- argonne offensive. and also, "by insisting that the aef operate as an independent force".

hope this
