Use the tоy dаtаset here fоr this questiоn. а) What is the mean for Y? [a_mean]. b) What is the standard deviation for Y? [b_std]. c) Construct a QQ plot for Y along with the normal QQ line. Note that the commands for producing the graph in R are in the accompanying formula sheet. Look at the three observations with smallest values for Y. These observations are in the bottom left of the graph. Choose the correct statement. (i) all three observations are above the line, (ii) at least one observation is above the line and at least one observation is below the line, (iii) all three observations are below the line. [c_iii]. d) Based on parts a-b and the QQ plot in c, does it seem reasonable to think that the variable Y represents a z value? That is, is it reasonable to think that Y follows the standard normal distribution and/or was constructed by taking the deviation from the mean and dividing it by the standard deviation? [d_yes]. e) Construct scatterplots of Y against Z1-Z4. Based on the scatterplots, which variable has the clearest positive relationship with Y? [e_z4]. f) Regress Y on all the other variables in the dataset. Which variable has the highest level of statistical significance? That is, for which variable would you reject the null hypothesis that the coefficient is 0 with the smallest value for
