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.

In real life, you will have your own datasets that are not built in. For a categorical variable, we can change the population proportion as we did in the example on Lesson 4.1.1.2. For a quantitative variable, we need to copy all of our data into StatKey. The video below walks through an example of copying data from Excel into StatKey. Determine the p value associated with the test statistic. From the output, the p value is 0.002. 4. Make a decision. p ≤ .05, therefore our decision is to reject the null hypothesis. 5. State a "real world" conclusion. There is evidence that in the population, on average, students' SAT-Math and their SAT-Verbal scores are different.Here's Hilton hospitality in the heart of hospitable Texas.
