Question 1 1 pts Select the statement(s) below that are characteristics or true statements for the Standard Normal Model. Select all that apply. O The shape is bell-curved. The shape is not symmetrical. The center of the model is 1 The mean of the model is 0 The spread of the model is 0. The standard deviation of the model is 1. The total area under the model curve is 1.5. The total area under the model curve represents 100% of the data. The area under the model curve represents probabilities. The horizontal scale is whatever variable x that is being studied. The horizontal scale is 'z! The formula to standardize any 'x' value is z = (point of interest - center) /spread
