Next, we're going to see if we can predict the Kinesthetic VARK scores of Biology students based on their Vi...
sorry i posted everytbjng bc it goes together. if you can help me with as much as you can thankyou Question 1 5 pts We're interested in whether Biology students have higher Visual relative to Kinesthetic learning styles. We've decided to use a paired t-test to investigate the question, based on our classroom as our sample. What assumptions do we have to make to use this method? our sample is an unbiased representative sample of the population both the Visual...
In Professor Friedman's economics course the correlation between the students' total scores before the final examination and their final examination scores is r = 0.52. The pre-exam totals for all students in the course have mean 276 and standard deviation 21. The final exam scores have mean 50 and standard deviation 9. Professor Friedman has lost Julie's final exam but knows that her total before the exam was 318. He decides to predict Julie's final exam score from her pre-exam...
In Professor Friedman's economics course the correlation between the students' total scores before the final examination and their final examination scores is r = 0.66. The pre-exam totals for all students in the course have mean 265 and standard deviation 39. The final exam scores have mean 90 and standard deviation 11. Professor Friedman has lost Julie's final exam but knows that her total before the exam was 320. He decides to predict Julie's final exam score from her pre-exam...

Standardized test scores are often used as part of an application to college. Test scores in math and verbal we between 200 and 800 but have no units Complete parts a through below a) Verbal and math test scores of a high school graduating class are displayed in the waterpiot, with the regression line added to the phone come ever below O A. The association between math scores and verbal scores is moderately linear and positive. Students with high math...
. A kinesiology major wanted to predict O2max based on the mile run. To develop the regression equation, she obtained O2max values (ml/kg/min) in the exercise physiology laboratory on 18 students. Two days later, she measured the same 18 students on the mile walk–run with scores reported as total time in seconds. The data are as follows. a. Using a computer, calculate the means, standard deviation, and correlation coefficient between the two variables. b. What is the probability that the...
The Excel file: DASSxlsx contains information recorded on a sample of 40 of the college students' responses. The file contains the DASScore (representing level of mood) and the Arxiety Score for each student Download the data file and fit a linear regression model for predicting DASSScore (Y) from AnxietyScore (0) Use your Excel output, and any other information provided to answer the following questions. For each question, either choose the most correct option, or type in the answer to the...
Erika Diaz Your name Assignment 10 Correlation, Scatterplot, and Prediction (due 7/30/20 - 1/4/20)(28 pts) 1. A teacher hypothesizes that the more days of school student misses, the worse the student will do on a final exam (possible scores on the exam range from 0 to 20). She obtained a random sample of 12 students. The data are shown below. Student days missed Final exam score 1 3 16 2 2 17 3 5 13 4 8 7 5 4...
IB math studies 1. Ten students were asked for their average grade at the end of their last year of high school and their average grade at the end of their last year at university.
