Question

Which of the following are conditions to check to determine if the sample mean will be approximately normally distributed?

Answer 1

To determine if the sample mean will be approximately normally distributed, there are several conditions that need to be checked: 1) The data should come from a simple, random sample. 2) The population should be approximately normally distributed. 3) The sample size should be large. 4) The population standard deviation should be known.

Step-by-step explanation:

To determine if the sample mean will be approximately normally distributed, there are several conditions that need to be checked:

1. The data should come from a simple, random sample.
2. The population should be approximately normally distributed.
3. The sample size should be large.
4. The population standard deviation should be known.

If these conditions are met, the sample mean will be approximately normally distributed.
