Answer:
5
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, we have that:
On average, how much error would be expected between the sample mean and the population mean?
This is the standard deviation of the sample. We have that . So
The answer is 5.
Answer:
C: .27
Step-by-step explanation:
Add the numbers 20, 11, 14, 30
20 + 11 + 14 + 30 = 75
Divide by what is the time the spinner landed on the letter A by the total
20/75 = .26666667
Round the number to the nearest hundredth and you get
.27
