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?

1. according to the internal revenue service, the mean tax refund for the year 2007 was $2,708. assume the standard deviation is $650 and that the amounts refunded follow a normal probability distribution. a. what percent of the refunds are more than $3,000? b. what percent of the refunds are more than $3,000 but less than $4,000? c. what percent of the refunds are less than $2,000?

Quadrilateral abcd is translated up and to the right, and then rotated about point q. which congruency statement is correct?
