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 standard 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%

Choose your answer from the following:

a) The pvalue of 0.022 indicates that the data provide strong evidence against HO: 0.90

HO is rejected at = 0.10.The status quo has changed

b) The pvalue of 0.006 indicates that the data provide overwhelming evidence against HO:

0.90.HO is rejected at = 0.10.Send out an air quality alert.

c) None of the answers are correct.

d) The pvalue of 0.062 indicates that the data provide weak evidence against HO: 0.90

HO is rejected at = 0.10.

e) The pvalue of 0.966 indicates that the data provide insignificant evidence against HO:

0.90. HO is not rejected at =0.10. The status quo remains unchanged.
