Ответ:
She should order 2400 coupons.
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.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
She would like 40% of customers in the population to receive the highest possible discount, with an SEP of 0.01 for this population.
This means that
How many coupons should she order?
We have to find n. So
She should order 2400 coupons.
