The National Center for Education Statistics monitors many aspects of elementary and secondary education. Their 1996 numbers are often used as a baseline to assess changes. In 1996, 31% of students reported that their mothers had graduated from college. In 2000, responses from 8368 randomly chosen students found that this figure had grown to 32%. Is this evidence of a change in education level among mothers? Write appropriate hypotheses.

An airplane has an airspeed of 500 kilometers per hour (km/hr) bearing $\mathrm{N} 45^{\circ} \mathrm{E}.$ The wind velocity is 60 km/hr in the direction $\mathrm{N} 30^{\circ} \mathrm{W}.$ Find the resultant vector representing the path of the plane relative to the ground. What is the ground speed of the plane? What is its direction?
