Answer:
The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
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.
For proportions, the mean is and the standard deviation is
In this problem, we have that:
.
So
The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
ML stands for milliliters. The prefix milli means 1,000. One liter contains 1,000 milliliters.
Therefore you want to convert the 200 mL to liters by dividing by 1,000. This gives you 200mL = 0.2L.
If you subtract the 0.2L from 1.2L you get 1L left.
