Webe) Redo the above best fit line using software (e.g., Excel), it would return the least squares estimate of the slope and intercept and re-calculate (𝛽𝛽) and (𝜂𝜂). Solution. See Excel worksheet. f) Given that the line fits in d) and e), does the appearance of the plot support the hypothesis that the data follows a Weibull distribution? Justify your response. WebScale parameter sigma_o = 246.1139. Therefore, the Weibull distribution for this dataset is: f (x) = (m/sigma_o) * (x/sigma_o)^ (m-1) * exp (- (x/sigma_o)^m) View the full answer. Step 2/3.
