Answer
In this study, the proportion is 0.3. Hence, H0 is true but 11 samples are those that do not support \[p=0.3\]
Therefore, this leads to a rejection of H0.
Work Step by Step
Type I error happens when H0 is rejected when it is true.
\[\alpha =p\left( T\text{ype I error} \right)\]
Hence, from the solution, 11 samples lead to rejection.
