A researcher is interested in determining whether the illumination level in a room affects how quickly clients can be put into a trance. The time (in seconds) it took for five clients to go into a trance when it was done in a room that was lit with low light was measured, as was the time it took for the same clients to go into a trance in a brightly lit room. The theory being tested does not predict which light condition will lead to going into a trance more quickly. The data are given below: what is the mD? SSD? est. ?D=? est. ?MD=?t=?Using the Oak Software, p=?

Low Light 45 15 75 30 57
Bright Light 49 13 82 30 60
