The distance, y, in miles, traveled by a car for a certain amount of time, x, in hours, is shown in the graph below:A graph titled Motion of Car is shown with Time in hours labeled on x-axis and Distance from Starting Point in miles labeled on y-axis. The scale on the x-axis shows the numbers 1, 2, 3, 4, 5, 6, and the scale on the y-axis shows the numbers 0, 14, 28, 42, 56, 70, 84. There are three straight lines in the graph. The first line joins ordered pair 0, 0 with 3, 42. The second straight line joins 3,42 and 4,42 and the third straight line joins ordered pair 4,42 with the ordered pair 5,56.Which of the following best describes the motion of the car shown? It travels for 2 hours, then stops for 1 hour, and finally travels again for 5 hours. It travels for 3 hours, then stops for 1 hour, and finally travels again for 1 hour. It travels for 3 hours, then stops for 4 hours, and finally travels again for 5 hours. It travels for 2 hours, then stops for 2 hours, and finally travels again for 1 hour.

A drug company claims that fewer than 1% of pills that it produces and ships fail to retain full potency after 60 days of production. An inspector inspects a shipment of medications to determine the efficacy in terms of the proportion p in the shipment that failed to retain full potency after 60 days of production. To do so, she selects an SRS of 200 pills. Suppose that eight of the 200 pills have failed to retain their full potency. The test statistic for the proportion of pills that have failed to retain their potency is:
