A study was conducted that resulted in the following relative frequency histogram. Determine whether or not the histogram indicates that a normal distribution could be used as a model for the variable. 0.4- 0.2- 0- 100 3000 4000 2000 5000 Choose the correct answer below. O A. The histogram is bell-shaped, so a normal distribution could be used as a model for the variable. O B. The histogram is not bell-shaped, so a normal distribution could not be used as a model for the variable. O C. The histogram is not bell-shaped, so a normal distribution could be used as a model for the variable. O D. The histogram is bell-shaped, so a normal distribution could not be used as a model for the variable.

Determine the area under the standard normal curve that lies between (a) Z= - 2.21 and Z= 2.21, (b) Z= - 0.65 and Z = 0, and (c) Z= 0.17 and Z= 1.27. Click the icon to view a table of areas under the normal curve. (a) The area that lies between Z = - 2.21 and Z= 2.21 is (Round to four decimal places as needed.) (b) The area that lies between Z = - 0.65 and Z = 0 is (Round to four decimal places as needed.) (c) The area that lies between Z = 0.17 and Z = 1.27 is (Round to four decimal places as needed.)
