An experiment was conducted to determine if the true mean performance scores of four randomly selected students regarding selected topics from Algebra 1 showed any significance differences over time. The four students were given the same task over three treatment times: (1) end-of-course, (2) one year after the course, and (3) two years after the course. Their performance score was recorded for each treatment time. The data from the experiment are displayed below.
| End-of-year | 1 year after | 1 years after | |
| Student1 | 5 | 4.5 | 4.5 |
| Student2 | 4.5 | 4 | 4 |
| Student3 | 4.8 | 4.3 | 4.0 |
| Student4 | 3.9 | 4.0 | 4.0 |
For this experiment, researchers were interested to see if there were any significant differences in mean performance scores based on the time after the course was completed. To analyze the data, they used a randomized block design and a significance level of 0.05.
For this experiment, what is T sub 1 ^2 ? What is B^2 sub 3?

7. Do diet sodas contribute to obesity? Researchers recruited 1,200 randomly selected college students at state universities in Texas to participate in a four- year study looking at the relationship between diet soda and obesity. At the start of the study, students were weighed and interviewed. After interviews w the students, participants were classified as either regular soda drinkers, diet soda drinkers, or non-soda drinkers. Four years after the interview, the students were contacted again and reweighed. The weight gains...

A professor wanted to determine whether an online homework system improved scores on a final exam. In the fall semester, he taught a class using the online homework system (which meant students did their homework online and received instant feedback about their answers along with helpful guidance). I spring semester, he taught a class without the homework system (which meant students were responsible for doing their homework the old-fashioned way - paper and pencil). The professor made sure to teach...

Forty students are selected to take part in an experiment testing the effect of espresso consumption on math test scores. The students are split into four groups of ten: a control group is given no espresso, another group is given a single espresso, another is given a double espresso, and the last is given a triple espresso. After the espresso is administrated, the students take a math test. The sample means and standard deviations of the results are: . •...

Randomly selected statistics students participated in an experiment to test their ability to determine when 1 minute (or 60 seconds) has passed. 44 students yielded a sample mean of 58.3 seconds. Assume that = 9.5 seconds. a) Use a 0.05 significance level to test the claim that the population mean is equal to 60 seconds. Claim: ---Select--- < > = ≠ ≤ ≥ 60 Ho: ---Select--- < > = ≠ ≤ ≥ 60 H1: ---Select--- < > = ≠ ≤ ≥ 60 b) What...

An agricultural researcher conducted an experiment to determine the effects of phosphorus (P) & potassium (K) fertilizer on the production of sugar from sugar beets. There were 3 treatments in her experiment, with 12 replicate fields for each treatment. These treatments were: • control (no fertilizer) • fertilizer added in December before winter plowing • fertilizer applied in April before sowing Prior to the experiment, two linear contrasts were planned: 1. control (treatment 1) vs. fertilizer added (treatments 2 &...

four randomly selected dogs were tasked with performing a trick. The time they took to perform the trick before and after being presented with a treat are as follows: dog 1: before=13 seconds, after=10 seconds dog 2 : before=15 seconds, after=16 seconds dog 3 : before=15 seconds, after=11 seconds dog 4: before=17 seconds, after=13 seconds let μD denote the true mean difference in before and after (calculated as before minus after), find the upper limit of a 95% confidence interval...

After randomly assigning subjects to treatments in a randomized comparative experiment, we can compare the treatment groups to see how well the randomization worked. We hope to find no significant differences among the groups. A study of how to provide premature infants with a substance essential to their development assigned infants at random to receive one of four types of supplement, called PBM, NLCP, PL-LCP, and TG- LCP. We are interested in whether the randomization results in equal proportions of...
