The psychology department of a large university maintains its own vivarium of rats for research purposes. A recent sampling of 50 rats from the vivarium revealed the following rat weights (grams): 320, 282, 341, 324, 340, 302, 336, 265, 313, 317, 310, 335, 353, 318, 296, 309, 308, 310, 277, 288, 314, 298, 315, 360, 275, 315, 297, 330, 296, 274, 250, 274, 318, 287, 284, 267, 292, 348, 302, 297, 270, 263, 269, 292, 298, 343, 284, 352, 345, 325A. Construct a frequency distribution of grouped scores with approximately 11 intervals.B. Construct a histogram of the frequency distribution constructed in part A.C. Is the distribution symmetrical or skewed?D. Construct a stem and leaf diagram with the last digit being a leaf and the first two digits a stem. Do not repeat stem values.E. Which diagram do you like better, the histogram or the stem and leaf diagram? Why?
