QUESTIONS:
BASED ON THE SAMPLE IS THERE SUFFICIENT EVIDENCE IN THE DATA TO CONCLUDE THAT THE POPULATION AVERAGE TIME TO DELOVER GOODS (DELIVERY TIME), ONCE THE ORDWR IS PLACED IS GREATER THAN 25 MINUTES? BASED KN STATISTICAL ANALYSIS WITH MARGIN OF ERROR = 5% WHAT IS YOUR CONCLUSION?
CHOICES:
A.) WE COULD NOT CONCLUDE ANYTHING.
B.) WE ACCEPT THE NULL HYPOTHESIS AND HENCE CONCLUDE THAT THE DELIVERY TIME IS MORE THAB 25 MIN.
C.) WE COULD NOT REJECT THE NULL HYPOTHESIS AND HEN E CONCLUDE THE MEAN DELIVERY TIME IS LESS THAN 25 MIN.
D.) WE REJECT THE NULL HYPOTHESIS AND HENCE CONCLUDE THE DELIVERY TIME IS MORE THAN 25 MIN.
YOU ARE INSTRUCTED TO PERFORM A STATISTICAL TEST TO FIND OUT IF THE DAY OF THE WEEK INFLUENCES THE MEAN GOODS DELIVERY TIME.
A.) WE COULD NOT REJECT THE NULL HYPOTHESIS; THE MEAN DELIVERY TIME IS NOT DIFFERENT FOR DIFFERENT DAYS OF THE WEEK.
B.) WE ACCEPT THE NULL HYPOTHESIS; THE MEAN DELIVERY TIME IS NOT DIFFERENT FOR DIFFERENT DAYS OF THE WEEK.
C.) WE REJECT THE NULL HYPOTHESIS; THE MEAN DELIVERY TIME IS DIFFERENT FOR EVERY DAY OF THE WEEK.
D.) WE REJECT THE NULL HYPOTHESIS; THE MEAN DELIVERY TIME IS DIFFERENT AT LEAST ON ONE OF THE DAYS OF THE WEEK.
WHAT STATISTICAL TEST WOULD YOU PERFORM TO TEST YOUR HYPOTHESIS: AVERAGE TIME TO DELIVER GOODS, ONCE THE ORDER IS PLACED OVER THE PHONE, IS MORE THAN 30 MINUTES IN THE POPULATUON.
A.) T-TEST
B.) Z-TEST
C.) ANOVA
D. LINEAR REGRESSION
BASED ON THE AVAILABLE SAMPLE DATA WHAT IS THE VARIANCE OF TIME TAKEN BY THE STUDENT WORKER TO DELIVER GOODS FOR A GIVEN ORDER?
A.) 15.4 MIN
