- To detect the presence of harmful insects in farm fields, we can put up boards covered with a sticky material and examine the insects trapped on the boards. Which colors attract insects best? Experimenters placed boards of several colors at random locations in a field of oats (four colors and six boards of each color). Make a plot of the number of beetles trapped on each board against the board's color, arranging the colors to show blue first, then white, then green, and last yellow (space the four colors equally on the horizontal axis).Dr. A. Ventura is interested in determining what kinds and how many pets people own in Bakersfield. He stands outside Petco and asks people what kind of pet they own.

- Refer to diagram and apply to multiple choice.As part of a sixth-grade class project the teacher brings to class a jar containing 200 gumballs of two different colors: red and green. Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar. Andy draws a sample of 25 gumballs, of which 8 are red and 17 are green. Use Andy's sample to estimate the number of red gumballs in the jar. There are approximately Answer red gumballs in the jar.A three-partner physician’s office generated $290,500 in profit the first year. Calculate the distribution based on original investment.
