Answer :
Final answer:
The probability that the mean number of t-shirts ordered is greater than 25 is D) None of the above.
Explanation:
To calculate the probability that the mean number of t-shirts ordered is greater than 25, we would need more information, specifically the mean and standard deviation of the t-shirt orders. Without this data, we cannot determine the probability with the options provided.
Statistical probability calculations typically involve the use of the mean (average) and standard deviation of a dataset, and the specific values provided in the options A, B, and C do not provide enough context to make a calculation. Therefore, the correct answer is D) None of the above because we lack the necessary data for a probability calculation.
In statistical analysis, when determining probabilities related to a dataset, it's crucial to have information about the distribution and the variability of the data. Without this information, we cannot make a meaningful probability calculation.
Therefore, the correct Option is Option D) None of the above
