The Casamigos tequila company produces two different types of tequila, silver and gold. They want to see if people rate the two types differently. If they find a statistically significant difference between the two, they will be able to charge a higher price for the higher rated type of tequila. To test their claim, they conduct a focus group with 275 participants. Each of the participants were asked to rate the tequila on a scale from 1 to 10, with...
