An exercise physiologist wants to examine whether stretching and wearing ankle weights affects running speed when exercising on treadmills. To carry out her study in 2005 she recruited 20 women who have roughly the same level of physical fitness, and randomly assigns five of the women into each of four groups: with or without ankle weights, and with or without a stretching period before using the treadmill. All the relevant assumptions and conditions for two-way ANOVA are satisfied. We wish to test if stretching has an effect on the running speed. The p-value of the relevant test is 0.127. Give your conclusion in the context of the problem. BIUST E E 3 WN- X X- Insert Formula
