Suppose a study is conducted to test the claim, at a 0.05 significance level that a population proportion is 30%. A simple random sample 680 subjects has a proportion of 35%. Determine the test statistic. (round to nearest hundredths as needed).© BrainMass Inc. brainmass.com June 3, 2020, 8:52 pm ad1c9bdddf
Given p^=0.35, n=690 and p=0.30. So, we can compute the test z-statistic
The solution determines the test statistic.
