Question

Allan is worried that students’ scores on examinations differ significantly based on the paper colors of the examinations, on average. Allan conducts an Analysis of Variance in which he selects four examinations at random for each of four paper colors.

Part A- If the value for Sum of Squares Total equals 2,144 and the value for Mean Squares Within equals 135.5, what does the calculated value for the associated test statistic equal?

Part B-If the level of significance equals 0.05, can Allan conclude students’ scores on examinations differ significantly based on the paper colors of the examinations, on average?

A researcher was interested in how students’ Graduate Record
Examinations scores (GREQ- Quantitative and GREV-Verbal) predict
college students’ graduate school Grade Point Average (GGPA). He
collects data from 30 college students. The GRE Quantitative (X1)
and GRE Verbal (X2) scores can range from 400-1600 (Note. This is
the old GRE score scale). GGPA (Y) can range from 0.00 to 4.00.
f. What proportion of variance in graduate grade point average
cannot be accounted by the variability in the quantitative GRE...

The College Board provided comparisons of Scholastic Aptitude
Test (SAT) scores based on the highest level of education attained
by the test taker's parents. A research hypothesis was that
students whose parents had attained a higher level of education
would on average score higher on the SAT. The overall mean SAT math
score was 514.† SAT math scores for independent samples of students

high school and those attending a local community college. He
selects a random sample of 210 students from the high school. The
mean and standard deviation of their fitness scores are 82 and 14,
respectively. He also selects a random sample of 210 students from
the local community college. The mean and standard deviation of
their...
