2. Modied Exercise 16 for Section 4.5 (pp. 254 in the textbook): The amount of paint required to paint a surface with an area of 50 m2 is normally distributed with mean 6 L and standard deviation 0.3 L. 1/3 (1) If 6.1 L of paint are available, What is the probability that the entire surface CANNOT be painted? (2) If 6.2 L of paint are available, What is the probability that the entire surface CAN be painted? (3) How much paint is needed so that the probability is 0.9 that the entire surface can be painted? (4) What must the standard deviation (if not 0.3 L) be so that the probability is 0.9 that 6.2 L of paint will be sufficient to pain the entire surface
