Question 1
Question - You had headcounts on Monday of 20 and Tuesday of 7 for a study of differences
in average police staffing across 3 adjoining precincts. You ran a chi-square study. You obtain
a p-value of less than :045. The Chi-Square test statistic has a value of 78.0 (greater than the
table value of critical chi-square for the F). What does your analysis show?
A - Not enough data was used
B - p is significant
C - p is NOT significant
D - p is borderline
CORRECT ANSWER
B - p is significant
• P-value less than 0.05 and high Chi-square stat
• Over 5 data points counted each day
Question 2
Question - You conduct a trend analysis. You find that R-square is over 0.8 and p-value is
0.023. What does your analysis show? You had 3 years of monthly incidence rates.
A - High R-square is good fit and low p is significant
B - Not enough data was used
C - High R-square is good fit but p is NOT significant

, D - R-square is Not a good fit but low p is significant
CORRECT ANSWER
A - High R-square is good fit and low p is significant
•P-value less than 0.05
• R-square greater than 0.5
• Over 30+ data points
Question 3
Question - Part of our success was the new point of sale system. Our customer sales
representatives were trained in utilizing the system to data mine and apply new marketing
techniques. They had to pass their final exam with a 90% or higher. What type of test is this?
A - Criterion referenced
B - Six Sigma

D - Norm referenced
CORRECT ANSWER
