1. Mental measurements of young children are often made by giving them blocks and telling them to build a tower as tall as possible. One experiment of block building was repeated a month later, with the times (in seconds) listed in the accompanying table (based on data from "Tower Building", by Johnson and Courtney, Child Development, Vol.3). The previous experiment shows that the times are normally distributed. Use a 0.01 level of significance to test the claim that there is no difference between the two times.
