We were interested in this topic to study because of the well known stereotype that women crave chocolate more than men. We wanted to know whether there was any science or data that could be collected to support this claim. Since Lucas works at Malley’s chocolate shop we knew this study could be done relatively easily. We are trying to show whether the stereotype of women craving chocolate more than men is legitimate or not.
We conducted an observational study to find whether the proportion of Malley’s customers was greater for men or women. We performed this study to see if the stereotype that women crave chocolate more than men was real or a myth. We also wanted to see if we would get the same results as the previous studies done on this same topic. One of us in the group works at a Malley's chocolate store, one that doesn’t sell ice cream, and this made it easy to conduct our study. We tallied each adult man and woman that entered the store on certain dates during our busiest hours. We grouped our tallied customers into 30 groups of 10 by the order that they came into the store. We then took our raw data and inserted it into a Minitab spreadsheet. We used our raw data and performed a 2 - proportion Z-test. Our null hypothesis was (proportion of women) - (proportion of men) = 0. Our alternative hypothesis was (proportion of women) - (proportion of men) > 0. The p-value that resulted from the test was very small, and below our alpha of 0.05. This led us to conclude that the proportion of women that shop at Malley's is higher than that of men that shop at Malley’s. We would extrapolate this data to North Olmsted Malley’s customers. The stereotype of women craving chocolate more than men might be true after all! We also created multiple graphs to show our findings.
