My Hw is about Random sampling and representing data by graphs. 1) Bar graph 2) circle graph 3) pictograph for categorical data. 1)Line plot 2) stem-and-leaf plot 3) histogram for Measurement data. Do only these questions : (29.3): 1, 2, 3, 6 (30.1): 3, 4, 6, 7, 8 generate graphs using technology. Do not do it by hand. It is easier. I upload our materials about the types of graphs. They may help.
