The speed at which people can read is typically measured in words per minute (wpm), which is just the average number of words a person can read within one minute. Suppose the distribution of reading speed for US adults follows a normal distribution with a mean of 200 wpm and a standard deviation of 40 wpm. Calculate the proportion of US adults who read faster than 122 wpm. Leave answer as a proportion NOT a percent and report the value to 4 decimal places.
