Question

Americans spend an average data of 5 hours per day online. If the standard deviation is 28 minutes , find the range in which at least 88.89% of a data will lie. Use chebyshev theorem

Answer 1

HERE IS YOUR ANSWER

Explanation:

To find the range in which at least 88.89% of the data will lie using Chebyshev's theorem, we need to calculate the number of standard deviations from the mean that corresponds to this percentage. According to the theorem, the range will be within k standard deviations from the mean, where k is the square root of the reciprocal of the desired percentage. In this case, k ≤ √(-9). However, since we cannot take the square root of a negative number within the real number system, we cannot determine the range using Chebyshev's theorem.
