Which means that 6 people take 0 minutes to eat breakfast (they probably had no breakfast!), 2 people say they only spend 1 minute having breakfast, etc. And here is the dot plot: Another version of the dot plot has just one dot for each data point like this:
Wetzel's Pretzels. Wetzel's Pretzels is a Pasadena, California-based franchise of fast-food restaurants. The first Wetzel's Pretzels location opened in 1994 at the South Bay Galleria in Redondo Beach, California. Currently, Wetzel's Pretzels has 300+ locations in the United States and six other countries worldwide. In 1996, Wetzel's began franchising their brand, and now has a co-branding relationship with Cold Stone Creamery, Juice It Up!, Swensen's and more.
The lye solution does at least two things for pretzels: It raises the pH of the pretzel's skin, which in turn makes the pretzel brown nicely as it bakes. Imparts that slightly bitter flavor. I don't think the salt used on pretzels is there to make up for a lack of salt in the dough. You can make pretzels that have plenty of flavor even without salt. I think the salt is there mainly because people like salt, because it adds a pleasing crunch, and because it's traditional -- it's part of what people (or at least Americans) expect from the pretzel experience.
