10. Show work when needed. A researcher wants to investigate the number of hours high school students spend doing
homework each night. After surveying 1,200 high school students, the researcher makes the
claim that she is 95% confident that the number of hours students spend doing homework each
night is between 0.6 and 2.8 hours.
a. What is the mean and margin of error for this confidence interval?

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
