Question: The sampling distribution of the difference between two means for independent samples . Question 9 options: tends to become normal as the sample sizes increase

The sampling distribution of the difference between two means for independent samples . Question 9 options: tends to become normal as the sample sizes increase is unknown and therefore one cannot test differences between two means against a null hypothesis is not subject to the Central Limit Theorem has a standard error equal to the difference in the standard errors of the individual samples
