When consumers apply from credit cards, their credit is rated using FICO scores.  A random sample of credit ratings is obtained, and the FICO scores are summarized with these statistics: n=35, ⴟ=660.3, s = 95.9. Use a = 0.05 and conduct a two tailed hypothesis test to test the claim that the mean credit score (of the general population) is equal to 700.
