If the majority of all students own a dog, then more than 50% own a dog. In this question we are comparing the population proportion for all World Campus STAT 200 students (i.e. p) to the value of 0.5. This is a single sampling proportion test. We want to know if the proportion is greater than 0.5, so this is a right-tailed test.Statkey will generally ask for the quantitative variable first and the categorical variable second if you are in a page that uses both types of variables.
