Answer 2

$\huge \mathtt{ \red {⋯} \pink{⋯}\purple{⋯} \blue {⋯} \orange{⋯} \green{⋯} \red{⋯}}$

range = maximum value - minimum value

maximum value in the given data is 165

minimum value in the given data is 150

range = 165-150

range = 15

$\huge \mathtt{ \red {⋯} \pink{⋯}\purple{⋯} \blue {⋯} \orange{⋯} \green{⋯} \red{⋯}}$
