Test HO - Proportion Proportion Question 9 (4 points ) An Air Quality instrument logs O 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 o Air Quality Values . Second at alpha = 0. 10 ( sensitive , exploratory ) , test the hypothesis tha proportion of times that air quality meets standards is at least 90% The pvalue of 0 96 6 indicates that the data provide insignificant evidence against HO : It 090 . HO is not rejected at a = 0.10 . The status quo remains unchanged The value of 0 06 indicates that the data provide overwhelming evidence against HO: I 2 090 . HO is rejected at a = 0 . 10 . Send out an air quality alert The pvalue of 0.22 indicates that the data provide strong evidence against HO : 1 2 0.90 HO is rejected at a = 0 . 10 . The status quo has changed None of the answers are correct The value of 0 062 indicates that the data provide weak evidence against HO : 1 2 0.90 HO is rejected at or = 0.10 Hide hint for Question The sample proportion is the mean of the Air Quality values Compute the mean to 4 decimal place accuracy . Test HO : 1 2 0.90
