The amount of paint required to paint a surface with an area of 50 m2 is normally distributed with mean 5.90L and standard deviation 0.3 L. What must the standard deviation be so that the probability is 0.9 that 6.2 L of paint will be sufficient to paint the entire surface? (Round the final answer to four decimal places.)
