5.    Thank you!!

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:

SSD=?

est. σ2D=?

est. σD=?

est. σMD=?

Estimate the effect size of the independent variable?

Low Light Bright Light
45 49
15 13

3.1. A researcher is interested in determining whether a new and cheaper method of analysis to determine the fat content of small organisms works as well as the older method used for many years. She has decided to split 15 samples and determine fat content in the two halves using the two methods. She has decided that simple linear regression will be the best method of analysis because she can test the hypothesis that the two methods give a 1:1...

A researcher is interested in determining whether typists are most productive in the morning, at midday, in the evening, or late at night. To answer this question, the researcher recruits 20 participants and assigns 5 participants to be measured at each time of day. To evaluate productivity, the researcher measures words typed per minute at each time of day. Answer the following questions considering the data below (alpha = .05) Morning Midday Evening Night 99 42 80 82 80 32...

Suppose you own a factory. You want to determine whether the level of illumination on the assembly line affects worker productivity. One day, you have one group of 5 employees work under very dim lighting, a second group of 5 employees work under a moderate level of light, and a third group of 5 employees work under very bright lights. The mean productivity (number of units assembled) for the low light group was 56; for the moderate light group, 68;...
