A restaurant association says the typical household spends a mean of $3568 per year on food away from home. You randomly select 12 households and find out how much each spent on food away from home per year. Can you reject the restaurant association's claim at alpha=0.05?

Ho: mu=3568 (claim)
Ha: mu=(with line through the = sign)3568
x-bar = 3418
s = 628.98
---
t(3418) = (3418-3568)/628.98 = -0.2385
------------
a) Find the P-value
p-value = 2*tcdf(-100,-0.2385,11) = 0.8159
-----
Since the p-value is greater than 5%, fail to reject Ho.
The test results support the claim.
