(a)

To determine

To make a scatterplot of the percent reacting as a function of the number of light pulses with two separate lines representing the two subpopulations and describe the shape of the relationship and find out what does it suggest about the pattern of withdrawal responses in the two subpopulations of C for increasing numbers of light pulses and how does your answer fit in the context of habituation and explain why these results suggest an involvement of PVD sensory neurons in nociception and habituation.

(b)

To determine

To use a software to obtain the statistical analysis of the linear regression of the percent reacting ( y ) as a function of the number of light pulses ( x1 ) and the indicator variable IndMutant ( x2 ) and find out what is the regression equation for this model.

(c)

To determine

To explain is the overall model significant and what percent of variation in percent reacting is explained by the model.

(d)

To determine

To explain are the regression coefficient for the two explanatory variables significant.
