A panel of dentists is interested in testing two different toothpaste brands (A and B) to see if there is a relationship between the brand and whether or not the patient has a cavity at their next appointment. A representative sample of 60 patients is recruited to take part in the study. At their first appointment of the year, each subject is assigned to brush their teeth with one of the two brands for the next six months. At their follow-up appointment six months later, they were checked for cavities. To test for significance of their findings, which of the following should the dentists use? Select one: a. Paired t-test b. One-sample t-test for a mean c. Linear Regression d. One-sample Z-test for a proportion e. Chi-Square test for independence f. Two-Sample t-test g. One-sample Z-test for a mean
