The File MT SAT Score.XLSX contains the results of a sample of 100 high school students SAT scores.  Use this data to perform a complete descriptive analysis including a histogram, boxplot and summary statistics associated with the observations.  Describe the shape spread and location of this data and discuss the presence of any possible outliers. Construct a normal probability plot for the SAT scores and discuss whether or not it would be reasonable to assume that this sample comes from a normally distributed population.  Construct a 95% interval estimate for the true mean SAT score for high school students taking this exam.  Include an interpretation for the interval you have constructed.
