Number 1 please Sometimes we are drawing samples from populations made up of groups that are of dif-Gnent sizes, as with the number of bass and the number of catfish in a particular lake. It is stillbuld bethat much better? THis quUJIvare, aridingwe wanted to draw samples of size 20 at random from a population having 56% in one groupand 44% in another (such as 56% for and 44% against), then we could select pairs of digitsfrom our random numbers. If a pair of digits is 01 through 56, then the pair represents a Jor. I1a pair of digits is 57 or more (and letting the pair 00 represent 100), then it represents an against.se ofdrawing names out of a hat. But for a large sample or a large number of samples, it iseasier to use random numbers from a table, calculator, or computer program. Simula-tions show that a sample statistic can vary from sample to sample.TAKE-AWAY MESSAGE..A random sample can be found in many ways, such as2olginsa 01 19Learning Exercises for Section 29.31./Jonathan wanted to find a sample of a population that is made up of two groups, onegroup with 35% of the population and the other with 65%.
