According to data released in
First, verify that the conditions of the Central Limit Theorem are met.
The Random and Independent condition holds assuming independence.
The Large Samples condition holds.
The Big Populations condition can reasonably be assumed to hold.
The probability is
(Type an integer or decimal rounded to three decimal places as needed.)
Final Answer: The probability is
Step 1 :First, verify that the conditions of the Central Limit Theorem are met. The Random and Independent condition holds assuming independence. The Large Samples condition holds. The Big Populations condition can reasonably be assumed to hold.
Step 2 :Given values are: sample size
Step 3 :Calculate the mean and standard deviation. The mean is
Step 4 :Calculate the z-score for
Step 5 :Calculate the probability using the cumulative distribution function (CDF) of the normal distribution. The probability is approximately 0.013, or 1.3%.
Step 6 :Final Answer: The probability is
