1. Write an m-file to construct the standard normal distribution table. 2. The heights of 50 students, measured to the nearest centimetres, have been found to be as follows: 161, 150, 154, 165, 168, 161, 154, 162, 150, 151, 162, 164, 171, 165, 158, 154, 156, 172, 160, 170, 153, 159, 161, 170, 162, 165, 166, 168, 165, 164, 154, 152, 153, 156, 158, 162, 160, 161, 173, 166, 161, 159, 162, 167, 168, 159, 158, 153, 154, 159 i) Construct the frequency table with histogram by MATLAB. Find measures of central tendency and locations. ii) iii) What can you conclude about their heights from the table? Q3. Investigate the above data by using linear and non-linear regression. Construct the models and obtain ANOVA Table for each model. Then, make a comparison. Which model is better and why?
