please answer all question 9-11
Question 9 2 pts z scores are useful because they: o reduce the probability of Type I and Type Il errors, allow permit the transformation of raw scores into percentiles. o transform linear scores into nonlinear scores, convert nonlinear scores back into linear scores, and allow us to obtain comparisons between nonlinear and linear scores. Pelation to the mean of its underlying population allow comparisons to be made between stores from different distributions, and permit...

Step 1 of 6: Find the estimated slope. Round your answer to
three decimal places
Step 2 of 6: Find the estimated y-intercept. Round your answer
to three decimal places.
Step 3 of 6: Determine if the statement "Not all points predicted
by the linear model fall on the same line" is true or false.
Step 4 of 6: Substitute the values you found in steps 1 and 2 into
the equation for the regression line to find the estimated...
