The boys’ and girls’ basketball teams at Roosevelt Middle School are selling baseball caps in order to raise money to buy new uniforms. To determine which cap sizes to order, they collect measurements of the head circumference (distance around the head) of the people buying a cap. The following data set represents the head circumferences, in mm, of the adults.
513, 525, 531, 533, 535, 535, 542, 543, 546, 549, 551, 552, 553, 554, 555, 560, 561, 563, 563, 565, 565, 568, 568, 571, 571, 574, 577, 580, 583, 583, 584, 585, 591, 595, 598, 603, 612, 618
The caps come in six sizes: XS, S, M, L, XL, and XXL. Each size covers a range of head circumferences.
