Astudent 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.
