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?

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.

An aircraft travels with the wind for 120 miles in 0.75 of an hour. The return trip is flown against the wind and takes exactly 1 hour.

Which system of linear equations represents x, the speed of the plane in miles per hour, and y, the speed of the wind in miles per hour? Recall the formula d = rt.

0.75 (x + y) = 120

x - y = 120

0.75 (x - y) = 120

x + y = 120

120 (x + y) = 0.75

120 (x - y) = 1

120 (x - y) = 0.75

120 (x + y) = 1
