A Restaurant That Bills Its House Account Monthly Is Concerned

A restaurant that bills its house account monthly is concerned that the average monthly bill exceeds
$200 per account. A random sample of twelve accounts is selected, resulting in a sample mean of
$220 and a standard deviation of $12. The t-test is to be conducted at the 5% level of significance.
Given the following printout, what can you determine?

A) The alternate hypothesis is μ ≤ 200
B) You should accept the null hypothesis at the 0.05 level of significance.
C) There is less than a 1% chance of getting these results if the null hypothesis is true, so you have very strong evidence to suggest that the average bill is more than $200.
D) There is less than a 1% chance of getting these results if the null hypothesis is true, so you have very strong evidence to suggest that the average bill is less than $200.
E) The alternate hypothesis is μ ≤ 200 and you should accept the null hypothesis at the 0.05 level of significance.
