Be sure to report the appropriate statistics. 1. A cognitive psychologist was interested in the ability to solve puzzles. They selected 24 college sophomores and matched them on the basis of IQ and assigned them, in groups of four, to one of four puzzle conditions (six blocks of four). The psychologist wants to make sure that all the puzzles are equally difficult. The dependent variable was the amount of time it took for a subject to complete the puzzle. The data are presented below. Were there differences in puzzle difficulty at the .05 level? Make sure to complete a 6-step hypothesis test.

In a research report, it is claimed that mice with an average life span of 32 months, will live to be about 40 months old when 40% of the calories in their food are replaced by vitamins and protein. Is there any reason to believe that μ < 40 if 64 mice that are placed on this diet have an average life span of 38 months with a standard deviation of 5.8 months? Use a P-value in your conclusion with α = 0.05.
