A student wondered if more than 10% of students enrolled in an introductory Chemistry class dropped before the midterm. He noticed that 2 out of 15 of his friends in the class dropped before the midterm. Based on his sample, he performed a hypothesis test. Is the hypothesis test a one-tailed or two-tailed test?Choose the correct answer below.A.It is a two-tailed test since the null hypothesis states that the parameter is not equal to the hypothesized valued.B.It is a two-tailed test since the alternative hypothesis states that the parameter is not equal to the hypothesized value.C.It is a one-tailed test since the alternative hypothesis states that the parameter is greater than the hypothesized value.D.It is a one-tailed test since the alternative hypothesis states that the parameter is not equal to the hypothesized value.E.It is a two-tailed test since the alternative hypothesis states that the parameter is greater than they hypothesized value.
Accepted Solution
A:
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.
