One of the primary advantages of a repeated-measures design, compared to an independent-measures design, is that it reduces the overall variability by removing variance caused by individual differences.

A milk processing company test implemented a plant-wide energy conservation program with a goal of reducing the mean daily consumption rate of at least 1,000 kWh from its normal operating plants. The conservation program was implemented in Plant B. The following data was collected on weekdays where consumption level is at its peak. Were the conservation efforts effective in achieving its goal? Compare the results with Plant A’s data where the program is not implemented using � = 0.05.

To improve driver safety, Federal government is always encouraging states to lower the variance of stopping distances of automobiles on wet roads. LDOTD engineers claim that the variance of stopping distances of automobiles on wet roads in Louisiana is really smaller than the variance of stopping distances of automobiles on dry roads because of the materials used to build the roads. To test the claim for allocation of highway funds, Federal Department of Transportation tested 16 automobiles traveling at the same speed for stopping distances on wet roads and then on the dry roads in Louisiana. On the wet roads the standard deviation of the stopping distances was 32 feet while on dry roads it was 16 feet. Test the claim at 5% level of significance.

Katrina Bell, analyst for the Hexaco Oil Company, has been assigned the task of investigating the claim that Hexaco dealers charge more for unleaded gasoline than do independent dealers. Katrina is afraid that if she chooses two independent random samples of stations for each type of dealer, the variability in price due to geographic location might be a factor. To eliminate this source of variability, she chooses a pair of stations : one independent and one Hexaco in close geographic proximity of each region. The results of the sampling are in Sheet 47. What should Katrina conclude at the 0.01 significance level?

In a study performed on comfort food eating during times of stress, it was found that mean rated comfort food consumption level (on a scale from 1-20) for a group of students undertaking their exam period was 14. In comparison, a group of students who were not undertaking exams or examination preparation had a mean rated comfort food consumption level of 10. The pooled estimate of the population variance was 64. What is the estimated effect size (d) of the study? 0.80 0.06 0.50 2.00
