- Hypothesis testing with One Way ANOVA. Use hypothesis testing to answer the research questions, labeling each step and completing any post-tests. Researchers want to know if surroundings make a difference in ability to remember a list of words. They test this by randomly assigning subjects to three conditions: shopping mall setting, driving in a car setting (simulation) and in an outdoor setting. Here are the memory scores for each condition: Mall Condition Driving Condition Outdoor Condition 8 8 15 7 7 10 8 5 12 6 8 9 9 10 14 12 10 10 7 12 8 8 8 10Luonpea Reattempt this question dudnsanOus When you are done, click here to see a summary of your score Question with last attempt is displayed for your review only In a certain school district, it was observed that 34% of the students in the element schools were classified as only children (no siblings).

- Among mammals, bears probably have the best sense of smell. You want to investigate this. You take food and place it in an airtight plastic container and randomly place it behind one of three panels. You repeat this 50 times. If the bear can correctly smell the food and press the panel with the food, he/she gets the food as a reward. You get the following results: Observed results Number of times the bear correctly presses the panel with food behind it: 43 Number of times the bear incorrectly presses one of the two panels without food behind it: 7 Can the bear smell the food? Give both the test statistic and the table value.You want to study whether music affects people’s ability to learn. You have 10 college students study a list of words with soft classical music playing, then you test how many words they correctly remember. You have 15 different college students study a list of words with loud heavy metal playing, then you test how many words they correctly remember. You want to compare the learning/memory of the two different groups. What kind of hypothesis test should you do? One-Sample z-test One-Sample t-test Independent-Samples t-test Related-Samples t-testChoose the correct definition of a random variable from the list below. A random variable is one whose values correspond to a scale with a countable number of values. one that occurs in one of two possible states, labeled success and failure. one that is measured to explain changes in the response variable. one whose values describe the outcome of some chance process. O one whose effect in an experiment cannot be distinguished from the effects of other variables.
- Think of all of the different games that have been presented in this lesson: rolling a die, using aspinner, drawing a card from a deck, etc. Sometimes the results ended favorably for one person overanother, but that’s not what we want for this activity. Can you design a fair game? Use this worksheet todesign a game whose expected value is 0. Be sure to define the rules of play. Prove that your game isfair using the expected value calculation.One control is beyond +2 s from the mean. How frequently would this occur on the basis of chance alone? why the correct answer is B ..please explain with pictures and explnation A. 1:100 B. 5:100 C. 1:400 D. 1:1600Describe a potential example of a "repeated measures t-tests" (see Ch. 11) that could be conducted within the social sciences, and list what you believe the outcome of the research would be for this study. No data or calculations are necessary whatsoever, but you should describe why you developed your chosen hypothesis (e.g., based on your own understanding of current research, real world observations, a wild guess, etc.).
