What are the probabilities that: Both have BERNIE hats One wears A MAGA hat and one wears a GND hats Neither wears a MAGA hat 4. (28) Calculate the statistics below using the following data on a sample of the variable X: Mean: Median Mode Range Variance Standard deviation Coefficient of variation Z score if x=15
