ASSIGNMENT RATS IN A MAZE: REVIEW OF DESCRIPTIVE STATISTICS C This is a good exercise for you to demonstrate your understanding of the concepts we've learned and test your computational skills You can Do this pl In a classic study examining the relationship between heredity and intelligence, Robert Try (1940) used a selective breeding program to develop separate strains of art and "dum nats" Tryon started with a large sample of lab rats and tested cach animalmaning problem. Based on their r scores es for the mare, Tryon selected the brightestats and the dullest rats from the sample. The brightest males were s ere mated with the brighned females Similarly, the challest rats were intabend. This process of testing and selective bling was continued for several generations until Tryn had established a line of mare-bright and separate line of mare dalla The following data represent results similar to those obtained by Tryon. The data consist of mare-leaming or scores for the original sample of seventh generation of mare-bright and the The table shows two sets of deta-Sample 1 is Original Rats & Sample 2 is the Maze-Bright Rats.
