Construct two histograms of the y-variable, one for each of the age groups in Excel. Choose \"insert statistical chart >> histogram\". Use \"select the data\" and highlight the column of interest. Include axis labels, and a legend. For both histograms choose the width of the bins to be 1.0. You can make this change by right-clicking the horizontal axis, choosing 'format axis', and inserting the desired bin width. 2. Considering your histograms, do the adult or youth age groups seem more susceptible to vitamin deficiency? 3. What statistical measures of location and spread will help you be more precise about the differences? Calculate those that you suggest using Excel, and comment on the patterns. In order to develop a statistical model of the difference between the two groups we postulate the following data generation process (see Lecture 14): _ - 2 Yadultj - ,u + 5 + Eaauw With Eaduit,i"N(0: Jaduit) _ - 2 Yyouch,i l\" + syouthi W'th syouthJNNa)! ayouth) Where ,u and 6 are unknown population parameters, and all errors are assumed statistically independent
