Suppose that quiz scores in a beginning statistics class have a mean of 7.6 with a standard deviation of 0.5. Using Chebyshev's Theorem, state the range in which at least 88.9% of the data will reside. Please do not round your answers.
Homework Answers
since from Chebyshev's Theorem , at least 88.9% of values are within 3 stanard deviation from mean
| corresponding interval = | (7.6-3*0.5,7.6+3*0.5)=(6.1 to 9.1) | ||||
