QUESTIONS WITH SOLUTIONS GRADED A+
◉ We collected 100 samples of size thirty of household income in
Arkansas with population mean, mu=50 (in thousands). the sample
mean, X and sample standard deviation, s, were recorded and the 95%
confidence interval for mu was taken for each sample. Given the 100
confidence intervals, how many do you expect to cover the population
mean mu=50? Answer: 95
**A 95% confidence interval implies that were the estimation process
repeated again and again, the 95% of the calculated intervals would be
expected to contain the true parameter value mu=50.
◉ Randominzation, stratified analysis, and matching. Answer: minimize
confounding
◉ Which of the following about the stage of change from the
Transtheoretical Model is true. Answer: Action refers to behavior change

behaviors?

level of aggressive behavior they are observing on school grounds and
decide to take action by trying and evaluating an intervention based
upon a new untested idea. Which of the folliwing tools might be the
most useful in designing the intervention program and the evaluation?
Answer: A logic model that describes program resources, activities, and
outcomes
