QUESTION: A Sound Quality instrument logs 0 when standards are not met and 1 when standards are met. The log is saved to file DATA (see below 2 columns - Data and Sound Quality).

- First, compute the proportion meeting standards as the mean of Sound Quality values.

- Second, at alpha 0.10 (sensitive, exploratory), test the hypothesis that proportion of times that sound quality meets standards is at least 90%.

(Note: The sample proportion is the mean of the Sound Quality values. Compute the mean to 4 decimal place accuracy. Test (null) H: 0.90.)

A) The p-value of 0.022 indicates that the data provide strong evidence against (null) H: 0.90. (null) H is rejected at (alpha) = 0.10. The status quo has changed.

B) The p-value of 0.966 indicates that the data provide insignificant evidence against H: 0.90. H is not rejected at (alpha) = 0.10. The status quo remains unchanged.

C) The p-value of 0.062 indicates that the data provide weak evidence against H: 0.90. H is rejected at = 0.10.

D) The p-value of 0.006 indicates that the data provide overwhelming evidence

against H: 0.90. H is rejected at = 0.10. Send out a sound quality alert.

E) None of the answers are correct.
