What does a correlation coefficient of 0 indicate? Choose the correct answer below. O A. There is no linear relationship between the two quantitative variables. O B. There is a weak relationship between the two quantitative variables. O C. It indicates a calculation error, as the correlation coefficient cannot be 0. O D. There is a strong relationship between the two quantitative variables. O E. It indicates a non-linear relationship between the two quantitative variables.
QUESTION 9 Solve the problem. The coefficient of variation, expressed as a percent, is used to describe the standard deviation relative to the mean. It allows us to compare variability of data sets with different measurement units and is calculated as follows: coefficient of variation- 100 (s/x Find the coefficient of variation for the following sample of weights (in pounds): 152 120 186 105 197 128 172 160 116 125 23.9% 19.1% 21.8% o 26.8% QUESTION 10 Solve the problem....

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...
