A desk manufacturer claims that the average time it takes to assemble a desk is 90 minutes with a standard deviation of 32 minut
stealth61 [152]

Answer:

The standard deviation of the sample mean is 4 minutes

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

The standard deviation of the population is 32.

Sample of 64.

So

s = \frac{32}{\sqrt{64}} = 4

The standard deviation of the sample mean is 4 minutes
