Question

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) and five pairs of children’ completion times are listed below. Test the claim that there is a difference in times between two trials. (a) At α = 5%, use the Classical approach to conclude it. (b) Using the P-value approach to conclude it. 1st Trial (A) 33 28 29 26 29 2nd Trial (B)30 25 24 24 29 .
