Present these two categorical variables together using an appropriate graph, and then discuss what the graph shows. [4 marks] Produce a contingency table to present these two categorical variables. Based on the contingency table, calculate the related empirical) joint and marginal probabilities. You may find helpful to produce another contingency table to show your calculated probabilities. (Hint: you may need Excel skills -- e.g. use the commands such as "sort" or "countif"- to count the relevant frequencies, or use PivotTable function) [8 marks] Based on the sample information, calculate the probability of either being a female or getting a low wage level, and calculate the probability of being a female conditional on getting a low wage
