Blood glucose levels for the obese patients have a mean of 100 with a standard deviation of 15. A researcher thinks that a diet high in raw raw cornstarch will have a positive or negative effect on blood glucose levels. A sample of 30 patients who had tried the raw cornstarch diet have a mean glucose level of 140. Using a 95% confidence level, test the hypothesis that the raw cornstarch had an effect.

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
