Plotting a scatter diagram

Reference no: EM1314474

An echo sounder is tested by observing the readings obtained at known depths. The results, in meters, are given in the following table.

Echo sound reading	6	18	35	41	50
Depth of water	8	20	30	36	40

i. Plot a scatter diagram of the results with Depth of Water as the independent variable.

ii. Determine the product moment correlation coefficient of the data correct to 3 decimal places.

iii. Determine the linear regression equation of Echo Sounder Reading on Depth of Water giving the coefficients correct to 3 decimal places.

iv. What reading would you expect in 25 meters of water?
