I need help with this please :)

How do you create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1?

Tabby sells clothing at a retail store, and she earns a commission of 6.25% on all items she sells. last week she sold a pair of jeans for $32.50, a skirt for $18.95, and 2 blouses for $14.95 each. what was tabby's total commission? a $4.15 b $5.08 c $81.35 d $348.60

Which is the focus of a parabola with equation y2=4x
