QuestionFind the range for at least $75\%$ of Americans' online time using Chebyshev's theorem, with an average of 4 hours and SD of 27 min.

Studdy Solution
Calculate the lower and upper bounds of the range.
$$Lower\, bound =240 -2 \times27 =186\, minutes$$$$Upper\, bound =240 +2 \times27 =294\, minutes$$At least75% of the data will lie between186 and294 minutes.
