For domestic plants ( sample 1 ), we have that the sample size is , the number of favorable cases is , so then the sample proportion is
For foreign plants ( sample 2), we have that the sample size is , the number of favorable cases is , so then the sample proportion is
The value of the pooled proportion is computed as
Also, the given significance level is .
