True or false When the necessary conditions are met a twotai
True or false: When the necessary conditions are met, a two-tailed test is being conducted to test the difference between two population proportions. The two sample proportions are p1hat=0.052 and p2hat=0.023 and the standard error of the sampling distribution of p1-p2 is 0.0085. The calculated value of the test statistic will be z = 3.41.
Solution
True
Z =( p1hat - p2hat)/std error
