A survey of the daily commuting times, in minutes, of seven different Chicago-based employees at a certain company yielded a data set consisting of the values 31, 14, 43, 32, 52, 23, and 44. A survey of the daily commuting times, in minutes, of seven different San Francisco–based employees at the same company yielded a data set consisting of the values 46, 31, 17, 33, 47, x, and 37. If the means of the two data sets are equal, what is the value of x?
