Question
The well-known psychologist Dr. Elb d this established what he alls his Generalized Anxiety Scale (GAS). The GAS, which is a sale fro f) o 10, measures the-general anxiety-of an individual, with higher GAS scores correspanding to i are anviety. (Dr. Elbod's assessment of anxiety is based on a vanety of measurements, both phys, loi al and psychological.) We're interested in making prediction s et out individuals' sleep behavior based on their GAS scores. The bivaniate data below give the GAS s re (denoted by x) and the number of hours of sleep last night (denoted by y) for each of the fifteer ad lts in a study. The least-squares regression line for these data has equation 841-029x. Thi: line, along with a scatter plot of the sample data, is shown in Figure 1.

Threr is only one question as I can see
and the answer is Greater than .
This happens because of the negative slope. If you observe the regression line , you can see there is a negative sign before the multiplier of x, which indicates that as x increases, y decreases and vice versa.
This can be said from the graph too. In the graph it is clear that for higher values of x we have lower y's , and vice versa. So, the answer is greater than.
If you still have diubts, let me know in the comment section. thank you
