The weight of baby elephants is believed to be Normally distributed, with a mean of 123.5 pounds. The average weight of a random sample of 35 baby elephants is found to be 125.7 pounds, with a standard deviation of 11.3 pounds. What is the standard error of the mean

The standard error of the mean is 1.91 pounds

Step-by-step explanation:

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

In this problem we have that:

So

The standard error of the mean is 1.91 pounds

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

there are infinitely many solutions.
