Coffee cups are all different sizes. but on average i would say a coffee cup can hold 8 fluid ounces or 1 cup. Hope this helps!! Need anything else just ask! :)
Answer:
The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem
![\mu = 20, \sigma = 3, n = 40, s = \frac{3}{\sqrt{40}} = 0.4743](https://tex.z-dn.net/?f=%5Cmu%20%3D%2020%2C%20%5Csigma%20%3D%203%2C%20n%20%3D%2040%2C%20s%20%3D%20%5Cfrac%7B3%7D%7B%5Csqrt%7B40%7D%7D%20%3D%200.4743)
The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours
