Does scatter plot of the data support this way? Yes, a scatter plot shows a reasonable linear relationship O No, scatter plot does not show a reasonable linear relationship (b) What proportion of observed variation in mist can be attributed to the simple linear regression relationship between velocity and we? Cound your answer to three decimal places) (c) The Investigators were particularly interested in the impact on mist of increasing velocity from 100 to 1000 (a factor of 10 corresponding to the difference between the smallest and largest x values in the sample), When x increases in this way, Is there substantial evidence that the true average increase in yis less than 0.67 (U 0.05.)
