Math one question WILL GIVE BRAINLIEST

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?

Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.

Me d is also an option but i couldn't get it in the picture
