Question 11 Suppose a statistician has calculated that the correlation between high school grades and university grades is r-1.08. Upon hearing this information, you would probably recommend to a university wanting to use the results that O high school grades are a poor predictor of success O high school grades are a good predictor of success O they hire a new statistician O at-test should have been used instead O a larger sample should be used to learn more about the relation

Question 10 Suppose you will perform a test to determine whether there is sufficient evidence to support a claim of a linear correlation between two variables. Find the critical values of r given the number of pairs of data n and the significance level a. n = 9, a = 0.01 Or= 0.798 r= 0.834 r= +0.666 r= +0.798

A group of university researchers wanted to determine the relationship that exists between the number of hours spent by a student in social media in a day (X) and their grade weighted average (Y). Twelve randomly selected students produced the following findings: Number of GWA Hours 4.0 95 8.0 85 87 89 91 85 89 86 84 96 82 85 7.0 6.5 5.5 9.0 4.0 10.0 7.5 2.0 12.0 9.0
Can someone help me out with these questions.

3. ACT scores are roughly Normal with mean 20.8 and standard deviation 4.8, and SAT scores are roughly Normal with mean 1026 and standard deviation 209. Some students take both. For those students, the correlation between the two scores is 0.72. a. What's the equation of the straight line that you'd use to predict ACT scores based on SAT scores? b. I got a 1300 on the SAT, and I'm planning to take the ACT. Predict what I might get, c. What's the equation of the straight line that you'd use to predict SAT scores based on ACT scores? d. My friend got a 27 on the ACT, and she's planning to take the SAT. Predict what she might get. e. How come you're predicting both that I'll do worse than her on the ACT and that she will do worse than me on the SAT? 4. Draw a simple random nlc of size 15 from the labels 40os01, 402.

This is two different samples though - younger students and older students. Paired samples T-test is for comparing the same group tested twice. Shouldn't the answer be correlation based on the us having two metric variables (age and number of complaints). We are testing whether, as age goes up, number of complaints also goes up, which you could see on a scatterplot using correlation?
