In this exercise, assume that the term "admission" refers to inpatient care, while "any use" refers to inpatient and outpatient care. The table below contains a lot of information. Without looking at any specific values, summarize what TYPE of data the table contains.

1. Give an example of a broad question about income levels and demand for health care that the table might have the potential to answer.

Predictions for enrollment popu- lation carried forward for all years of the study. The t-statistics are corrected for intertemporal and intrafamily correlation. The statistics test the null hypothesis that the mean of middle (highest) third equals the mean of the lowest third; for example, the 4.91 figure implies we can reject at the .001 level the hypothesis that in the free plan the likelihood of any use for the lowest and middle thirds of the income distribution are equal.Table 3.2: Meal options in the Grossman model.
