Question

Questio volunteers In a study to investigate whether cow's milk produces mucus, 125 Australian assigned to drink either cow's milk or a soy milk placebo. ns 6-8: Both drinks were were randomly a cocoa-peppermint flavoring that effectively disguised the feel of cow's milk and the after taste of soy milk so that both drinks looked and tasted the same. After drinking their assigned drink, as "coating over subjects indicated the extent to which they experienced any mucus indicators suc mouth," "mucousy back of throat," etc. 6. What is the factor? A. cow's milk, soy milk B. mucus indicators er cow's milk produces mucus D. type of m E. the 125 volunteers 7. Which of these terms fits best with chis study? A. experiment B. observational study C. dependent samples D. generalization inference E. degrees of freedom 8. What was the purpose of randomly assigning the subjects to cow's mils or soy milk? A. so that the cause of any significant differences in mucus indicators could be attributed to the source B. so that the results could be generalized to all adults, not just the Australian volunteers C. so that the data distributions would be nearly-normal D. so that the subjects' responses would not be biased by their knowledge of what drink the E. so that a paired-samples analysis could be done
