Taco Bell, the percentage - because it is derived from the sample - is the sample
statistic.
Observation studies have the advantage of allowing observation of consumers' motives,
attitudes, and intentions.

An experiment is defined as manipulating a dependent variable to see how it affects an
independent variable while controlling for the effects of a complex variable.
Packaged information is a type of secondary data in which the data collected and/or the
process of collecting the data are prepackaged for all users.
Which of the following is true and should be remembered when developing questions?

no bias.

In bivariate regression analysis, the higher the Adjusted R Square value:
A) the lower the predictive power of the analysis.
B) the better the straight line's fit to the scatter points.
C) the worse the straight line's fit to the scatter points.
D) the closer to 0 it will be.
E) None of the above; there is no Adjusted R Square value in regression analysis.
________ are defined as errors committed by the individuals who administer
questionnaires, typically interviewers.

___ 36 to 50
___ over 50

C) interval.
D) ratio.
E) age-related.
In the formula for a straight line, the intercept is known as:
A) the dependent variable.
B) the variable used to predict the dependent variable.
C) the change in y for any unit change in x.
D) the point where the line cuts the y axis when x =0.
E) b.
Bivariate regression analysis is defined as a predictive analysis technique in which:
A) a pattern is identified over time and projected into the future.
B) a relationship that exists across time is observed to make a prediction.
C) one variable is used to predict the level of another by use of the straight-line
formula.
D) one variable is used to predict the level of another by use of a scatter diagram.
E) a relationship that exists at one point in time is observed to make a prediction.
A predictive model is an approach to prediction that:
A) relates the conditions expected to be in place influencing the factor that is being
predicted.
B) observes a consistent pattern over time.
C) identifies a pattern and projects it into the future.
D) uses past experience to predict the future.
E) uses current experience to explain the past.
If we were comparing the difference between the mean number of sports drinks
consumed by males versus females, and we calculated a z value of 6.43, we would
conclude that:
A) the probability of support of the null hypothesis of no difference is less than .01
because 6.43 is greater than 2.58.
B) the probability of support of the alternative hypothesis of no difference is less than .
01 because 6.43 is greater than 2.58.
C) the probability of support of the null hypothesis of no difference is less than .01
because 6.43 is less than 2.58.
D) the probability of support of the alternative hypothesis of no difference is less than .
01 because 6.43 is less than 2.58.
E) there is a 6.43 percent chance that the two means are not significantly different.

Jane is concerned about an error in the problem statement of a research study she has
conducted for her company. The error:
A) can be controlled using a larger sample size.
B) can be measured and, therefore, controlled.

You run bivariate regression analysis and you find that the ANOVA results indicate that
you have Sig. value for your F of .05. Now, looking under your Coefficients output, you
have an intercept value and a slope value. You should use these values only when:
A) they are both significant, i.e., have Sig. values above 1.00.
B) they are both significant, i.e., have Sig. values below 1.00.
C) they are both significant, i.e., have Sig. values equal to or below .05.
D) at least one is significant, i.e., has a Sig. value above .80.
E) None of the above; because the F value in the ANOVA was not significant, you
should not have even looked at the Coefficients output.
