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%. O The pvalue of 0.062 indicates that the data provide weak evidence against H0: 11 2 0.90. H0 is rejected at or = 0.10. 0 None of the answers are correct. 0 The pvalue of 0.966 indicates that the data provide insignificant evidence against H0: 11 2 0.90. H0 is not rejected at or = 0.10. The status quo remains unchanged. 0 The pvalue of 0.022 indicates that the data provide strong evidence against H0: 1': 2 0.90. H0 is rejected at O( = 0.10. The status quo has changed. 0 The pvalue of 0.006 indicates that the data provide overwhelming evidence against H0: at 2 0.90. H0 is rejected at o: = 0.10. Send out an air quality alert. v Hide hint for Question 11 The sample proportion is the mean of the Air Quality values. Compute the mean to 4 decimal place accuracy. Test H0: 11 2 0.90
