7.52. A Time Magazine article titled "Wal-Mart's Gender Gap" (July 5, 2004) stated that in 2001 women managers at Wal-Mart earned $14,500 a year less, on the average, than their male counterparts. Ifyou were also given the standard errors of the annual mean salaries for male and female managers at Wal-Mart, would you have enough information to determine whether this is a "statistically significant" difference? Explain.
