Testing Hypothoses, P-Value method

hey there guys, this question (and topic) is throwing me through a loop.

Heres the question:

**When consumers apply for credit, their credit is rated using FICO scores. A Random sample of credit ratings is obtained, and, the fico scores are summarized w/ these stats: n = 18, x(bar)=660, s =95.9. **

Use a .05 significance lvl to test the claim that these credit ratings are from a population with a mean that is equal to 700. If the bank of newport requires a credit rating of 700 or higher for a car loan, do the results indicate that everyone will be eligible for a car loan, why or why not?

So, tbh im not entirely sure what im doing here.

I wrote the problem in the following way

**(660-700)/(95.9/(18)^(1/2)) = -1.76961**

The degrees of freedom are n-1 (17)

I assume its a two tailed test, and I have the area in two tails 2.567

I take the significance level and divide it by two and get .025

and I have no idea where to go after that. Any help is appreciated
