Women's heights average 65 inches with a standard deviation of 2.2 inches in a certain study. Use the 68-95-99.7 rule to determine the typical ranges of thewomen's heights. In what range will approximately the middle 95% of the women's heights lie?C.The middle 95% of the women's heights will lie between and(Simplify your answers. Type integers or decimals. Use ascending order.)

Answer 1

• We are told that the average height : Mean () = 65

,

• Standard deviation : SD () = 2.2

• 95 % 0f women height range = +- 3

= 65 +-3( 2.2)

= {65 + 6.6 ; 65 -6.6}

= {71.6 ; 58.4}

• This means that 95 % 0f women height will range between ( 58.4 ) and (71.6 )
