   Question

   Below are two formulas for calculating the standard error of the sampling distribution of a proportion, namely, respectively the standard error (se) and the exact standard error (se₀). When do you use which formula? 

   

   

   
   
   1. TRUE: You use the standard error (se) when calculating a confidence interval and the exact standard error (se₀) when testing a hypothesis.
   2. FALSE: You use the standard error (se) when calculating a t-distribution and the exact standard error (se₀) is used in the Standard Normal Distribution (the z-distribution).
   3. FALSE: The standard error (se) you use for sample distribution and the exact standard error (se₀) for the sample distribution.
   4. FALSE: You use the standard error (se) for the alternative hypothesis (H_a) and the exact standard error (se₀) use for the null hypothesis (H₀).
   5. FALSE: You use the standard error (se) for a categorical variable and the exact standard error (se₀) in the case of a quantitative variable.
   
   
   1. True
   2. False
   3. False
   4. False
   5. False
