Suppose we want to claim more than 70% of plastic bottles are never recycled. 200 bottles were randomly selected and tracked. If we know that a sample proportion of 77% will result in a test statistic (z score) of 2, which of the following sample proportion will result in a test statistic that is more than 2? a) 85% b) 65% c) 70% d) 76%
