1)     A process of filling water bottles has a mean of 16.07 and an average range of 0.31. The company does not want water bottles processed above a weight of 16.3 ounces or below a weight of 15.7 ounces. Six bottles were sampled each time. Calculate the C_pk.

A.   1.01

B.    1.34

C.    0.82

D.   0.63

 

2)     What is true about the process in question 25?

A.   CPU is higher than CPL; the process average is closer to the LSL

B.    C_pk is lower than 1.00; the process is not capable at 3 sigma level

C.    CPL is higher than CPU; the process average is closer to the USL

D.   Both A and B are correct

E.    Both B and C are correct

 

Use data in worksheet named Q27-29 to answer question 27-29 (attached).

A rural police force would like to investigate the relationship between the amount of time to complete an obstacle course (Minutes) and age of their police officers (years).

 

3)     What is the correlation coefficient between age and completion time of the obstacle course?

A.   .325

B.    .469

C.    .672

D.   .997

 

4)     Is the correlation statistically significant at the alpha=.05 level?

A.   Absolutely, a correlation that high must be statistically significant

B.    Yes, the test statistic falls within the rejection range

C.    No, the test statistic does not fall within the rejection range

D.   Need more data points to compute this

 

5)     Which variable is the dependent variable (age or completion time)?

A.   Age is the dependent variable

B.    Both age and completion time are dependent on one another

C.    The completion time is the dependent variable

D.   Completion time is the independent variable
