Majesty Video Production Inc. wants the mean length of its advertisements to be 24 seconds. Assume the distribution of ad length

oksano4ka [1.4K]

Answer:

It is going to be bell-shaped(normally distributed), with mean $\mu = 24$ and standard deviation $s = \frac{2}{\sqrt{15}} = 0.5164$ .

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $\frac{\sigma}{\sqrt{n}}$ .
