Answer:
C.It is a one-tailed test since the alternative hypothesis states that the parameter is greater than the hypothesized value.
Step-by-step explanation:
Let p be the percentage of students enrolled in an introductory Chemistry class dropped before the midterm. Then null and alternative hypotheses are:
[tex]H_{0}[/tex]: p=10%
[tex]H_{a}[/tex]: p>10%
The alternative hypothesis states that the parameter is greater than the hypothesized value.
