PLEASE ANSWER ALL QUESTIONS ACCORDINGLY
Is there a relationship between brain size and intelligence? The Performance IQ scores (PIQ) and brain sizes (in pixels, as measured by MRI scans) of 40 subjects were measured. A researcher used simple linear regression using brain size to predict PIQ and reported the following results. Variable Standard error Intercept (Bo) Coefficient 1.74 0.0001203 42.39 Brain size (1) 0.0000465 34. The researcher decided to ignore the p-value from the test of the null hypothesis: Ho: B₁= 0 stating that such a test is meaningless when the slope is obviously very close to zero. Do you agree with this researcher (yes/no?) and then justify (explain) your option (5 points). A) Agree B) Disagree *** Please remember to explain it.
