Answer:
Each distribution has a different mean and a different standard deviation.
Step-by-step explanation:
The mean of a data set is the middle number. So, the number/place in the middle of each graph should be considered.
And from observing these graphs, they are all bell curves. The middle of a bell curve is the mean, and the *steeper the bell curve, the smaller the standard deviation. *
-The orange and blue graphs are barely overlapping, so their middle number of the data set must not be shared. (indicating that the mean must be different).
-The steepness and height of each bell curve is different, indicating that the standard deviation must be different
*{why? : If there are more values/numbers/outcomes that are close to the mean, (which would look like a very tall bell curve), the standard deviation (standard deviation is how spread out the values are from the mean on average) is much smaller. }*
The steeper the bell curve, the smaller the standard deviation.
