Hey Guys! I have a practice sheet that involves the use of tinker plots so If any of you know how to use this software I'd love to see how to solve these so I can use them as a reference when practicing! Below is the questions along with the 60 pieces of data. Thanks yall!

Lyric Readability In May 2015, data analysts at SeatSmar-tl examined the lyrical readability (reading-level) for over 200 songs to examine whether music lyrics are getting \"dumber\". Each song's reading-level was operationalized using the FleschKincaid score. This score quanties the reading-level by indicating the grade-level a person would need to comprehend the lyrics. For example, Beyonce's hit song, Irreplaceable, has a readability score of 3.9, indicating that a person with slightly less than a fourth-grade reading level would comprehend the vocabulary used in the song's lyrics. In this assignment, you will use the SeatSmart data (available in brie-readability?) to answer the following research question: Is the lyric readability for newer songs (released alter 2005) less than that for older songs (released in or prior to 2005)? Each question is worth lpoint unless otherwise indicated. Explore the Observed Data Open the We-readabigng; le in TinkerPlots. Create a single plot of the obserwd data to compare the reading-levels between recent and older songs. Also include the numerical mean values for each group on the plot. 1. Copy-and-paste (or sketch) the plot of the observed data, with the averages included, into your word-processed document. Use the groups' mean values to compute the derence in means for the two groups. Subtract the recent average from the older average. (Your answer should be a positive number.) 2. Report the observed difference in means. 3. What does the observed result (the difference in means) suggest about the answer to the research question? Explain. 4. Why do you need to conduct a simulation in order to determine whether recent songs have a smaller readability than older songs? Explain why you cannot answer the research question using just the observed result. (Zpts) Bootstrap Test 5. Write the null hypothesis for the bootstrap test. Set up a TinkerPlots sampler to generate different bootstrap samples of the data under the model specied in the null hypothesis (Hint: You did something similar to this in the Murderous Nurse activity). 6. Copy-and-paste (or sketch) a picture of the TinkerPlots sampler window into your word- processed document. 7. What repeat value did you use for your sampler? Explain why you chose this value. 8. Did you use with or without replacement for the readability scores in the sampling device? Explain your choice. 9. Did you sample with or without replacement for the group labels (newer and older) in the sampling device? Explain your choice. Simulate using the Model Use TinkerPlots to carry out 500 trials of the bootstrap simulation. Create a plot of the 500 bootstrapped differences in means. Evaluate the Observed Results 10. Describe the shape of the distribution of the 500 simulated results. Also compute and report the mean and standard deviation of this distribution. 1]. Explain, by referring to the null hypothesis, why we could have expected the mean you computed in Question #10. Add a reference line to the plot of the distribution of the 500 simulated results at the value of the difference in the observed data. 12. Copy and paste (or sketch) the plot (with the reference line) into your word-processed document. 13. Use the plot from Question #12, to compute the pvalue. Show your work. Answer the Research Question 14. Based on the pvalue you computed, how compatible is the observed difference in means with the results produced by the model specied in the null hypothesis? What does this suggest about the answer to the research question? Explain.
