An Air Quality instrument 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%.

OPTIONS:

A. The pvalue of 0.062 indicates that the data provide weak evidence against H0: 0.90. H0 is rejected at =0.10.

B. None of the answers are correct.

C. The pvalue of 0.966 indicates that the data provide insignificant evidence against H0: 0.90. HO is not rejected at 0.10. The status quo remain unchanged.

D. The pvalue 0f 0.022 indicates that the data provide strong evidence against H0: 0.90. H0 is rejected at = 0.10. The status quo has changed.

E. The pvalue of 0.006 indicates that the data provide overwhelming evidence against H0: 0.90. H0 is rejected at 0.10. Send out an air quality alert.
