Q15 Please answer the fill-ins The accompanying data was read from a graph. The independent variable is SO₂ deposition rate (mg/m²/day) and the dependent variable is steel weight loss (g/m²).| x | 13 | 18 | 38 | 43 | 45 | 114 ||-----|-----|-----|-----|-----|-----|------|| y | 260 | 350 | 470 | 590 | 560 | 1220 |### (a) Construct a scatter plot.#### GraphsThere are four scatter plots depicted, each comparing the SO₂ deposition rate (x-axis) to the steel weight loss (y-axis). They all show data points clustered in a linear fashion, indicating a possible linear relationship between the two variables:- **Scatter Plot 1:** Shows the data points scattered from x = 0 to x = 120 with corresponding y-values from y = 0 to y = 1200.**Question:** Does the simple linear regression model appear to be reasonable in this situation?- Options: - Yes, the scatter plot shows a reasonable linear relationship. (Selected) - No, the scatter plot does not show a reasonable linear relationship.### (b) Calculate the equation of the estimated regression line. (Round all numerical values to two decimal places.)\[ y = \_\_\_\_ \]### (c) What percentage of observed variation in steel weight loss can be attributed to the model relationship in combination with variation in deposition rate? (Round your answer to one decimal place.)\[ \_\_\_\_ \% \]### (d) Because the largest x value in the sample greatly exceeds the others, this observation may have been very influential in determining the equation of the line. Delete this observation and recalculate the equation. (Round all numerical values to two decimal places.)\[ y^* = \_\_\_\_ \]

(b) Use EXCEL to determine the regression equation. EXCEL procedure: Go to EXCEL Go to…
