A study was conducted that resulted in the following relative frequency histogram. Determine whether or not the histogram indicates that a normal0.4 distribution could be used as a model for the variable. 0.2- 1000 2000 3000 4000 5000 Choose the correct answer below. OA. The histogram is bell-shaped, so a normal distribution could not be used as a model for the variable. OB. The histogram is bell-shaped, so a normal distribution could be used as a model for the variable. OC. The histogram is not bell-shaped, so a normal distribution could be used as a model for the variable. The histogram is not bell-shaped, so a normal distribution could not be used as a model for the variables
