Answer:
Atleast 93.75% of data lies between 15 and 31.
Step-by-step explanation:
We are given the following in the question:
Mean = 23
Standard deviation = 2
We have to find he data lying between 15 and 31.

Thus, we have to find the data lying within 4 standard deviation from the mean.
Chebyshev's Theorem:
- According to this theorem atleast
percent of data lies within k standard deviation of mean. - For k = 4.

Thus, atleast 93.75% of data lies between 15 and 31.
