Select the correct response. For a research study, there are five options for the first question, four options for the second question, and three options for the third question. Using a list, there would be outcomes for the sample space. For a similar study, if there are only four options for the first question, the sample space would have outcomes.
Favorite Skittles Flavor?A poll sampled 75 people, asking them their favorite skittle flavor by color (green, orange, purple, red, or yellow). A separate poll sampled 98 people, again asking them their favorite skittle flavor, but rather than by color they asked by the actual flavor (lime, orange, grape, strawberry, and lemon, respectively). The table below shows the results from both polls. Does the way people choose their favorite Skittles type, by color or flavor, appear to be related to which type is chosen?

A J.D. Power and Associates vehicle quality survey asked new owners a variety of questions about their recently purchased automobile. One question asked for the owner's rating of the vehicle using categorical responses of average, outstanding, and exceptional. Another question asked for the owner's education level with the categorical responses some high school, high school graduate, some college, and college graduate. Assume the sample data below are for 500 owners who had recently purchased an automobile. Education Quality Rating Some HS HS Grad Some College College Grad Average 30 30 20 60 Outstanding 50 50 50 90 Exceptional 20 20 30 50 a. Use a 0.05 level of significance and a test of independence to determine if a new owner's vehicle quality rating is independent of the owner's education. Compute the value of the x test statistic (to 2 decimals). Use Table 3 of Appendix B to find the p-value. The p-value is - Select your answer - What is your conclusion? - Select your answer - v…

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 100 marbles from the bag. Of the 100 marbles, 32 are red. The data collection method can best be described as Survey Census Controlled study Clinical study The target population consists of The 1100 marbles in the bag The 300 red marbles in the bag The 32 red marbles drawn by the student The 100 marbles drawn by the student None of the above The sample consists of The 300 red marbles in the bag The 32 red marbles drawn by the student The 100 marbles drawn by the student The 1100 marbles in the bag None of the above Based on the sample, the student would estimate that marbles in the bag were red.
