A national computer retailer believes that the average sales are greater for salespersons with a college degree. A random sample of 32 salespersons with a degree had an average weekly sale of $3422 last year, while 33 salespersons without a college degree averaged $3366 in weekly sales. The standard deviations were $468 and $642 respectively. Is there evidence at the 5% level to support the retailer's belief? Select the [p-value, Decision to Reject (RH0) or Failure to Reject (FRH0)].
