The top few hits from a search engine claim that approximately 10% of the population in the United States is left-handed. From a random sample of 20 students at your high school, you find 6 left-handed students, which gives you reason to believe that the true parameter is greater than 10%. Use the drop-down menus to complete the statements.

Using a random number table, let digits
represent left-handed individuals and let digits
represent right-handed individuals.

Moving left to right across a row, select
numbers at a time and record the proportion of left-handed individuals.

The  steps that will verify that a parallelogram is a rectangle are written below  

(2) Calculate the lengths of all sides, and show that both pairs of opposite sides are congruent.

(4) Calculate the midpoints of each diagonal, and show the diagonals bisect each other.

The rectangle and the parallelogram both have some similarities that are listed below

In both rectangle and parallelogram

Hence option 2 is correct which states that

Calculate the lengths of all sides, and show that both pairs of opposite sides are congruent.

Also from third similarity

We can say that option 4 is also correct which states that

Calculate the midpoints of each diagonal, and show the diagonals bisect each other.
