- I'm not sure what this question is asking and how do I resolve it.The test is not a t-test it's a different one but I forgot which one was itBad model? A student who has created a linear model isdisappointed to find that her R2 value is a very low 13%.a) Does this mean that a linear model is not appropriate?Explain.b) Does this model allow the student to make accuratepredictions? Explain.
- Need help with this question. Thank you :)Please show all work so I can understand! Thank you!i need help step by step how to solve this i do not understand the process here. Conduct a hypothesis test to answer the following research question. Be sure to clearly state each step of a hypothesis in your response as well as indicating your critical regions, computing obtained statistic and drawing a conclusion. Does prenatal exposure to alcohol impact birth weight (test n = 16 newborn rats) Population Values : μ = 18 grams σ = 4 grams Sample Mean: M = 15 grams
- Statistics question... chapter theory of attributesReview of Independent t-test Base your answers on the following problem and data. A student researcher wants to test the hypothesis that students who are made to feel anxious by a critical teacher cannot learn math concepts as well as students who are assigned to a supportive teacher. For the student's 301 project, the student recruits 14 participants and randomly assigns the participants to learn new math concepts from either a critical (n=7) or supportive teacher (n=7). All other variables are kept the same; in fact, a single person performs the roles of both the supportive and critical teacher, but just modifies her behavior accordingly. Each group of participants then takes a test after the math lesson and their scores on the test are measured. Here is the resulting data: Critical Teacher 27 25 19 10 16 22 14 Supportive Teacher 25 29 18 23 20 15 19
