Fast Food Fast By Monica McGrath & Christine Malikowski
History • Fast Food restaurants have been around since 1921 when the first White Castle opened. • First hamburger invented in 1916. • First drive-thru restaurant invented in 1948. • December 12, 1948 First McDonalds opened • Burger King open in the1950s and Wendy’s came along in 1969
Is going thru the Drive Thru faster then going Inside the Restaurant to get Fast Food?
How Did It Happen • Picked a SRS of 3 types of each restaurant by using yellowpages.com • At each place we gathered 10 times from getting food inside and 10 from going through the drive thru.
The Subjects • Burger King 1 • 60 Easton Rd Warrington, PA 18976 • Burger King 2 • 580 W Street Rd Warminster, PA 18974 • Burger King 3 • 560 N Main St Doylestown, PA 18901 • Chick-fil-A 1 • 160 Easton Rd Warrington, Pa 18976 • Chick-fil-A 2 • 4 West RoadNewtown, PA 18940-4301 • Chick-fil-A 3 • 2500 W Moreland Rd Willow Grove, PA 19090 • KFC 1 • 1865 Easton Rd Willow Grove, PA • KFC 2 • 490 N Main St Doylestown, PA 18901 • KFC 3 • 1719 N Broad St Lansdale, PA 19446 • Wendy’s 1 • 620 EASTON ROADWARRINGTON, PA 18976 US • Wendy’s 2 • 400 N Main St Doylestown, PA 18901 • Wendy’s 3 • 755 York Rd Ste 204 Warminster, PA 18974 • McDonalds 1 • 2395 York Rd Jamison, PA 18929 • McDonalds 2 • 210 Inverness Cir Chalfont, PA 18914 • McDonalds 3 • 39 Doyle St Doylestown, PA 18901
Inside Times Min = 1.04 Q1 = 1.29 Med = 2.10 Q3 = 2.53 Max = 3.54 Outside Times Min = 1.01 Q1 = 1.59 Med = 2.25 Q3 = 2.50 Max = 3.56 5 Number Summary
The Tests • Test 1- 2-Sample T-test testing whether the average drive thru time is equal to the average inside time • Test 2- Mean difference test, Testing weather the average drive thru time found is equal to the national average for each restaurant visited

Test One µ1 = Inside times µ2 = Drive Thru times Ho: µ1= µ2 Ha: µ1> µ2 T= = -1.1533 P(t > -1.1533 | df = 27.6011) = .87007
Conclusions • We fail to reject ho because the p-value of .87007 is less then α = .05. • We have sufficient evidence that the average times of going through the drive thru of a fast food restaurant is greater then going inside.
Confidence Interval • X ± (t*)(s/ n) =( -.295, .62834) • We are 99% confident that the mean difference of Drive thru times and inside times is between -.295 and .62834 mins.

Test Two Ho:µd = 0 Ha: µd ≠ 0 T= = 4.0414 P( t > 4.0414|df = 4) = .0156
Conclusion • We reject Ho in favor of Ha because the p-value of .0156 is greater then α = .05. • We have sufficient evidence that the observed drive thru times were not equal to the national drive thru averages.
Margin Of Error • ordering different things or amount in which you order • different time of day (how busy) • Number of people on shift • who serves you • timing not accurate(human error)
Personal Analysis • The collection of data we did find somewhat difficult just because of the huge amount of data needed. • We started out by buy all the food ourselves but then reverted to just timing people because of costs. • Project was fun but challenging
Personal Thoughts Cont. • The Results for test one were surprising because we expected the drive thru times to be faster. • The results for test two were surprising also because they did not fit the national averages
Application • We find this applicable to any person wanting to get food in a hurry. • Not always is what people try to advertise is always true. • Fast restaurant = WENDY’S
