Answer:
By the Central Limit Theorem, the mean is 78, the standard deviation is 
and the shape is approximately normal.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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.
Mean of 78 and a standard deviation of 6
This means that 
Samples of n:
This means that the standard deviation is:
What are the mean, standard deviation, and shape of the distribution of x-bar for n?
By the Central Limit Theorem, the mean is 78, the standard deviation is and the shape is approximately normal.
The variable for x is twenty eight
The two sizes chosen for this item are a quart and one gallon.
The first one is advantageous because when it is desired that this be brought some place, it will not be very bulky and not heavy because among the given, this is the smallest. Also, one gallon can be chosen because it does serve many people at a relatively lower price than the other given.
Oh yay, proportional thinking! (Vicious sarcasm). Alright, let's do this:
<span>Volume of the cylinder = </span><span>π(h)r^2
New volume = </span><span>π(h/3)(4r)^2
= (1/3)</span><span>π(h)(16r^2)
=16*(1/3)</span><span>π(h)r^2
=(16/3)</span><span>π(h)r^2
Therefore, it's D. Though it's spelled pi, and you should really use the ^ symbol. </span>
