n = 487; x = 48

Suppose we take a random sample of 487 students and find the number, 48, who have taken a statistics course.

Use 1PropZTest to test that the proportion of students is more than 0.15. Include the following:

1. The null and alternative hypothesis with correct symbols using the Equation Editor.
2. Use a significance level of 0.01
3. State input values in the TI to find the p-value and make a decision about the null hypothesis. Justify your decision.
4. Type a conclusion about the alternative hypothesis.
