In 2016, more than 200,000 students took the AP®Statistics exam. Of these students, 14% earned the highest score of 5. You want to find the probability that a random sample of 300 students who took the 2016 AP®Statistics exam would beat that number by having 15% or higher scored a 5.
Step 1: Does this meet the 10% condition? Explain how you know
Step 2: Does this meet the large counts condition? Explain how you know
Step 3: Find the probability that a random sample of 300 students who took the 2016 AP®Statistics exam would indicate that 15% or higher scored a 5.
Answer rounded to the nearest hundredth
How do you know?
Answer rounded to the nearest tenth
What condition needs to be met in order to calculate the standard deviation of the sampling distribution? Do we meet this condition?
Calculate the standard deviation of the sampling distribution.
Answer rounded to the nearest thousandth
Interpret the standard deviation of the sampling distribution
Answer rounded to the nearest hundredth
What is the Mean of the sampling distribution of p̂
Answer rounded to the nearest hundredth
What condition needs to be verified before we can calculate the Standard Deviation of the sampling distribution of p̂? Verify that the condition is met.
Find the standard deviation of the sampling distribution of p̂
Answer rounded to the nearest thousandth
What condition needs to be verified before we know that the sampling distribution of p̂ is normally distributed? Verify that the condition is met.
Answer rounded to the nearest thousandth
Explain why or why not.
Answer rounded to the nearest thousandth
Answer rounded to the nearest thousandth
Explain your reasoning.
Verify the 10% condition is met. Why is this important?
Verify the Large Counts condition is met. Why is this important?
Find the mean of the sampling distribution of p̂c-p̂a
Round the nearest Hundredth
Find the standard Deviation of the sampling distribution of p̂c-p̂a
Round the nearest Thousandth
Round the nearest Thousandth
