Discount percent =
Discount percent =
Discount percent = 0.3804 * 100
Discount percent = 38.04%
Hence,
The discount was 38.04%
Answer:
The standard error of a proportion p in a sample of size n is given by:
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
In this question:
The standard error of a proportion p in a sample of size n is given by:
Answer:
<h2>g = 30</h2><h2 />
Step-by-step explanation:
1/4 (g + 2) = 8
g + 2 = 8 (4)
g = 32 - 2
g = 30
