Use the runs test to determine whether the given sequence is random. Use a significance level
of 0.05. A sample of 30 clock radios is selected in sequence from an assembly line. Each
radio is examined and judged to be acceptable (A)or defective (D). The results are shown
below. Test for randomness. $\begin{array} { l }
\text {A A D A A A D A A D }\
\text {A D A A A D A A A A }\
\text {A A D D A A A A D A }\
