Altomonte’s is an authentic Italian Market that takes pride in preparing the highest quality food “just like mom used to do at home”. Using “the finest luncheon meats and cheeses”, they create quality sandwiches and hoagies “served on crusty Italian bread” which is baked fresh daily in their own bakery.

overview of project
Overview of Project

We want to explore the ordering habits of the customers who eat at Altomonte’s Italian Market .

  • We will test for the…
  • Percentage of customers who actually order Italian items
  • Association between the type of meats ordered and the gender of the customer
  • Proportion of male customers who order large sizes compared to female customers
  • Association between the order method and the gender of the customer

We will collect all of the order slips over a three-day period and randomly select 50 customers from each day to generate our study sample.

These slips will provide all customer ordering information, allowing us to easily conduct our tests.

1 proportion z test italian items ordered
1-Proportion Z-Test: Italian Items Ordered

Overall, there is a larger percentage of non-Italian items ordered than Italian.

Females are very normally distributed, with a nearly equal proportion of the population ordering Italian items to the proportion ordering non-Italian.

Males are very slightly skewed, demonstrating a preference towards non-Italian items.

hypothesis
Hypothesis

* We chose our null hypothesis assuming that all sandwiches are enjoyed equally. Dividing the three Italian choices (Italian, Delux, and Meatball) by the thirteen offered options in total, the proportion came out to be 0.23.

Ho: p=0.23

Ha: p>0.23

Z= =6.6014

P(z>6.6014)=2.0464 x 10-11

Calculations

Based on the results of our 1-Proportion Z Test, we can infer that customers who order from Altomonte’s tend to favor the Italian items on the menu.

Conclusions

We reject Ho because our p-value < α= 0.05.

We have sufficient evidence that the true proportion of Italian items ordered is greater than 0.23.

2 proportion z test number of large hoagies ordered
2-Proportion Z-Test:Number of Large Hoagies Ordered

Overall, there is a greater number of large hoagies ordered than small hoagies.

Males had a greater difference in the amount of smalls ordered versus the amount of larges ordered than females. Yet, both gender populations demonstrate a greater interest in larger sized hoagies.

hypothesis1
Hypothesis

*1=Male

2=Female

Ho: p1=p2

Ha: p1>p2

* We chose our alternative hypothesis stating that males would order a greater number of large hoagies compared to females. We chose this because we felt that since males tend to eat more, they would choose a larger sized hoagie than females.

Z= =0.9272

P(z>0.9272)=0.1769

Calculations

Based on the results of our 2-Proportion Z Test, we can infer that customers—no matter if they are male or female—who order from Altomonte’sare more likely to order a large hoagie.

Conclusions

We fail to reject Ho because our p-value > α= 0.05.

We have sufficient evidence that the true proportion of males who order large hoagies is equal to the proportion of females who order large hoagies.

chi square test for association cold cuts vs gender
Chi-Square Test for Association:Cold Cuts vs. Gender

Overall, there is a larger percent of females who ordered Italian hoagies compared to the males.

Males seemed to have ordered more hoagies categorized as “other” than females.

Overall, females seem to have larger percentages in most of the cold cut categories compared to the males.

…=6.0375

P( >6.0375|df=7)=0.5354

Calculations

Based on the results of our chi-square test, we can infer that males and females that order from Altomonte’sshow no difference in preference of cold cuts on their hoagies.

Conclusions

We fail to reject Ho because our p-value > α= 0.05.

We have sufficient evidence that there is no association between gender and cold cut.

chi square test for association order method vs gender
Chi-Square Test for Association:Order Method vs. Gender

Overall, there is a larger number of customers who placed their order at the store rather than calling it in for pick-up.

Males had the large majority of orders that were placed at the store compared to that of females.

We believe that the males could have placed more orders while present at the store because perhaps they didn’t plan ahead/were too lazy; unlike the females.

Calculations

Based on the results of our chi-square test, we can infer that males and females that order from Altomonte’sshow no difference in placing their order at the store or over the phone for pick-up.

Conclusions

We fail to reject Ho because our p-value > α= 0.05.

We have sufficient evidence that there is no association between gender and order method.

bias and error
Bias and Error
  • Orders written down incorrectly
  • Excluding “Other” category in Italian proportion test
  • Using only one Italian deli
  • Restricted to people only in the area
personal opinions
Personal Opinions

Data:

  • Males order more large-sized hoagies than females
  • Females order by call and pick-up method more than males

Project:

  • Retrieving and analyzing data time consuming process
conclusion
Conclusion
  • Many people order Italian selections
    • Given there are three hoagie selections considered “Italian” and ten that are not, Altomonte’s is maintaining its Italian reputation
  • Females order large-sized hoagies just as much as males
  • Gender doesn’t make a difference in cold cut preference
  • Males call in their orders for pick-up just as much as females
