Statistical Concepts: • Probability • Binomial Probability Distribution Calculating Binomial Probabilities NOTE: For question 1, you will be using the same data file your instructor gave you for the Week 2 lab. 1. Using the data file from your instructor (same one you used for the Week 2 lab), calculate descriptive statistics for the variable (Coin) where each of the thirty-five students in the sample flipped a coin 10 times. Round your answers to three decimal places and type the mean...
