1. Answer:

The standard error of the mean for a sample size of 100 is 1.5.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation, which is also called standard error,

In this problem, we have that:

Calculate the standard error of the mean for a sample size of 100.

This is s when n = 100. So

The standard error of the mean for a sample size of 100 is 1.5.
