Given the following information, Slope = 4.72; Y bar-712.2; x-65.4, the estimated regression function will be 8. a. y 403.51+ 4.72 X b. y -3296.1 +4.72X c. y 10.89+4.72X d. y- 56577.8+4.72 9. Standard deviation is a measure of: Association b. Differences c. Dispersion d. Correlation e. None of the above 10. The standard error of the mean will be for samples. a. smaller; larger b. smaller; smaller c. larger; larger d. larger, non-probability e. none of the above 11- This measure of central tendency can be computed only from interval or ratio data. a. mode b. median c. mean d. all of the above must be computed from interval or ratio data e. none of the above can be computed from interval or ratio data 12. If we conclude that the average weekly amount of soft drink consumption by males and females is about the same, but that the standard deviation among males is greater than that for females, what would this mean? a. males and females pretty much agree as to how many soft drinks they consume per week b. males consume more soft drinks per week than females c. even though males and females consume, on average, about the same number of soft drinks, there is more diversity of consumption among males none of the above d
