Laboratory 2 Sperm whales ( Physeter microcephalus ) are among the deepest ocean divers among mammals. A team of marine mammal researchers attached time-depth recorders to sperm whales in the Pacific and Atlantic oceans to record individual diving depth for dives lasting longer than 30 minutes. The results of the study are presented below, in meters. Pacific sperm whales: 420, 729, 442, 529, 484, 720, 453, 1002, 561, 980, 806, 263, 897, 652, 575, 346, 794, 553, 410, 417, 830, 1050, 1196, 687, 629, 1125, 496, 673, 998, 62, 735, 628, 1082, 1014, 732, 474, 111, 716, 567, 646, 286, 531, 550, 1346, 1401, 949, 644, 787, 929, 756, 763, 1035, 631, 1235, 395, 302, 804, 388, 574, 568, 491, 1389, 1125 Atlantic sperm whales: 619, 285, 415, 756, 288, 435, 473, 487, 512, 552, 795, 544, 472, 731, 290, 772, 674, 387, 670, 271, 648, 323, 344, 399, 817, 616, 396, 597, 594, 363, 332, 457, 456, 125, 566, 884, 801, 560, 442, 722, 374, 485, 370, 343, 658, 425, 424, 489, 480, 431, 602, 576, 348, 331, 432, 538 Copy and paste ea ch dataset into R. Don’t forget to define the datasets with a name using the c( ) function, and remember: capitalization, spacing, and parentheses are important when using datasets and functions in R! 1) Use the stem() command to create a stem-and-leaf plot for each dataset and copy and paste it below (6 points).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
