An air quality instrument logs 0 when standards are not met and 1 when standards are met. The log is saved to file DATA. First, compute the proportion meeting standards as the mean of air quality values. Second, at alpha=0.10 (sensitive, exploratory), test the hypothesis that proportion of times that air quality meets standards is at least 90%.
