Solution

Meaning of high/low standard deviation:
Standard Deviation measures how much your entire data set differs from the mean.
$∙$ The larger the standard deviation, the more spread or variation is in the data or the higher the standard deviation the more variability or spread we have in the data.
$∙$ Small standard deviations mean that most of the data is clustered around the mean.
Hence, high/low standard deviations are stated above.
