please help me solve sub-part d Fitts' Law is a robust and highly adopted model of human movement. According to Fitts' Law, thetime T required to move and select a target of width W that lies at a distance (or amplitude) A isT = a + b log2(2A/W)%Dwhere a and b are constants estimated using simple linear regression. The quantity log,(2A/W) istermed the Index of Difficulty (ID) and represents the independent variable (measured in "bits") inthe model. Research reported in the Special Interest Group on Computer-Human Interaction Bulletin(July 1993) used Fitts' Law to model the time (in milliseconds) required to perform a certain taskon a computer. Based on data collected for n = 160 trials (using different values of A and W), thefollowing least squares prediction equation was obtained:Î = 175.4 + 133.2(ID)%3Da. Interpret the estimates, 175.4 and 133.2.b. The coefficient of correlation for the analysis is r = .951. Interpret this value.c. Conduct a test to determine whether the model using Fitts' Law is statistically adequate forpredicting performance time. Use a = .05.d. Çalculate the coefficient of determination, r². Interpret the result.
