The mean and standard deviation of the sample data collected on continuous variable x are −0.25 and 0.03, respectively. The following table shows the relative frequencies of the data in the given intervals

The graph shown

Step-by-step explanation:

The line y = -3x is the one shown in the image. To test if this region matches the inequality take a point within the region shown in the image and then substitute it in the inequality, if the inequality is satisfied then the plotted region is correct.

Let's test (-3, 0) the point that clearly lies within the shaded region.

zero is less than nine. Then the inequality is satisfied and the shaded region represents the inequality of
