Attendees at an outdoor concert can buy pavilion tickets (A) or lawn tickets (B). Below is the output for the one-sample runs to test whether there is a pattern in 32 consecutive ticket purchases. Runs Test

$\begin{array}{|l|l|l|}
\hline\text { n }&\text { runs }\
\hline 21 & 6& \text { A }\
\hline 11 & 6& \text { B }\
\hline 32 & 12& \text { total }\
\hline
\end{array}$

15.44 expected value
$2.50$ standard deviation
$- 1.17 z$
$.2403$ p-value (two-tailed) The best conclusion at ? = .05 would be:
A)the pattern is random.
B)there is a difference in medians.
C)the sample sizes are too small.
D)the sample sizes must be equal.

The p-value is greater than .05, so we fail to reject the null hypothesis that the pattern is random. Therefore, the best conclusion is that the pattern is not statistically significant and is likely due to chance.
