As part of a sixth-grade class project, the teacher brings to class a large 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 20 gumballs, of which 8 are red and 12 are green. Use Andy's sample to estimate the number of red gumballs in the jar. Approximately how many red gumballs are in the jar? Use whole numbers.

Step 1
- Red gumballs in sample = 8 - Total gumballs in sample = 20 - Proportion of red gumballs in sample = 8/20 = 0.4 Show more…

As part of a statistics project, a teacher brings a bag of marbles containing 800 white marbles and 300 red marbles. She tells the students the bag contains 1100 total marbles, and asks her students to determine how many red marbles are in the bag without counting them. A student randomly draws 150 marbles from the bag. Of the 150 marbles, 45 are red. The data collection method can best be described as Clinical study Census Survey Controlled study The target population consists of The 45 red marbles drawn by the student The 150 marbles drawn by the student The 1100 marbles in the bag The 300 red marbles in the bag None of the above The sample consists of The 150 marbles drawn by the student The 1100 marbles in the bag The 300 red marbles in the bag The 45 red marbles drawn by the student None of the above

You buy a big bag of 50 gumballs. There are five different colors of gumballs in the bag and you are curious if each of the colors were equally likely to be put in the bag - or whether some colors were more likely than others. a. If all five colors were equally likely to be put in the bag, what would be the expected number of gumballs of each color? b. Suppose that you open the bag of gumballs and separate them into five piles by color: You find that you have 8 red, 7 green, 16 orange, 7 yellow, and 12 blue. Determine the chi-square test statistic if the null hypothesis is that the colors of the gumballs occur with equal frequency:
