Item 1
Tab a: Describe the dataset using appropriate plots/curves/charts,… (7)
Tab b: Consider one of continuous attributes, and compute central and variational measures.
Tab c: For a particular variable of the dataset, use Chebyshev’s rule, and propose one-sigma interval. Based on your proposed interval, specify the outliers if any.
Tab d: Explain how the box-plot technique can be used to detect outliers. Apply this technique for one attribute of the dataset.

Item 2:
Tab a: Select four variables of the dataset, and propose an appropriate probability model to quantify uncertainty of each variable.
Tab b: For each model in part (a), estimate the parameters of model.
Tab c: Express the way in which each model can be used for the predictive analytics, then find the prediction for each attribute.
Item 3:
Tab a: Consider two categorical variables of the dataset, develop a binary decision making strategy to check whether two variables are independent at the significant level alpha=0.01. To do so,
State the hypotheses.
Find the statistic and critical values.
Explain your decision and Interpret results.
Tab b: Consider one categorical variable, apply goodness of fit test to evaluate whether a candidate set of probabilities can be appropriate to quantify the uncertainty of class frequency at the significant level alpha=0.05.
Tab c: Consider one continuous variable in the dataset, and apply test of mean for a proposed candidate of at the significant level alpha=0.05.
