I have sent you the instructors information, what i started on which will have the survey i am doing, and a past submission. My testing is dining experience inside and outside. For inside the number will be 19 or select the number of tables you want and outside will be 14. Any questions I will continue to check back. I need this by Monday the 17th so i can format or ask questions and have time to meet the deadline. Thanks

QA 345-E01:
Chapter 11: Two Sample Tests of Hypotheses
DUE DATE: Sunday, April 30, 2016
The short project/experiment is directly related to Learning Objective 2 from Chapter 11.
Your final submission must be TYPED using the report format below.
Points will be deducted for failure to follow directions.
For this experiment, you must select two items to compare their means. Here are possible examples:
•
•
•
•
•
•
•
•
•
Mean Checkout time at Walmart’s regular lane vs Mean Checkout time at Walmart’s self-check
Mean Wendys’ drive thru time vs. Mean McDonald’s drive-thru time
Order and fulfillment time at McDonald’s vs. Order and Fulfillment time at Wendy’s (can be a
combination of inside and drive-thru)
McDonald’s inside time vs McDonald’s drive thru time
$ Amount spent at Walmart vs $ Amount spent at Kroger
Pizza Hut delivery time vs Papa John’s delivery time
Zaxby’s service time vs Chic Fil A service time
Travel time to work on route 1 vs. Travel time to work using route 2.
Mean number of white cars on your way to school vs the mean number of black cars.
*NOTES:
1. You are not limited to the examples I have listed above. These are some that students have
done or suggested before. You can do any two mean comparisons.
2. If you do the amount of money spent at two different stores, you do not have to use
Walmart and Kroger, but any two stores that you shop at (Dollar General vs Family Dollar;
Walmart vs Kmart; etc.)
3. You do not have to use the specific restaurants listed above. You can use any restaurants
that you visit. However, of course if one is fast-food, the other must also be fast food (so
you can’t compare Applebee’s order fulfillment time vs McDonald’s order fulfillment time).
4. Your minimum sample size for each must be 5 . So if you do McDonald’s drive thru vs
McDonald’s inside, you must record the time from at least 5 drive thru experiences and at
least 5 inside ordering experiences.
5. The sample sizes do NOT have to be identical for the two samples. You could go through the
drive thru 5 times and order inside 8 times.
6. For checkout time, ordering/fulfillment time, drive thru time, you should use the total
time from entering the line until you receive your order.

Running head: TWO SAMPLE TEST OF HYPOSTHESIS
SHUCKUM’S OYSTER PUB AND SEAFOOD GRILL
DINING INSIDE VS OUTSIDE

TWO SAMPLE TEST OF HYPOSTHESIS
OVERVIEW
The data was obtained at Shuckum’s Oyster Pub and Seafood Grilling, located in Panama
City Beach, Florida. Many diners never consider wait times for being served inside or outside.
Even, a consideration at times is not considered if it is louder inside, more comfortable inside, or
if service is better. Personally, I prefer the outdoor dining experience where one can people
watch, which can break that awkward silence sometimes we all experience at a dinner table.
Each table that was observed was over the course of a two-hour period. I am sure the
outside waitress hated me for taking so long, when they need to turn their tables much quicker.
It was obvious the first hour observing those eating outside had a much more pleasant experience
than those dining inside. Conversations were happening all around, people smiling, laughing,
and just truly enjoying themselves and the scenery on Front Beach Road. In fact, most that came
from dining inside I couldn’t see the same departure satisfaction. Those who came from inside
the restaurant didn’t linger, couldn’t get out of there fast enough, or even glimpse and smile at
anyone outside.
