The Mean Gross Annual Incomes of Certified Tack Welders Are

The mean gross annual incomes of certified tack welders are normally distributed with the mean of
$50,000 and a standard deviation of $4,000. The ship building association wishes to find out
Whether their tack welders earn more or less than $50,000 annually. The alternate hypothesis is
That the mean is not $50,000.
Given the following megastat printout, what conclusions can be made?

A) There is a 1.68% chance of getting these sample results if the annual income is actually $50,000.
B) Since the p-value is 7%, we reject the null hypothesis at a 5% level of significance.
C) Since the p-value is 9%, we have insufficient evidence to reject the null hypothesis at the 5% level of significance.
D) Since the p-value is 9%, we reject the null hypothesis at the 1% level of significance.
E) Since the p-value is incredibly small (far less than 1%) , we reject the null hypothesis at the 1% level of significance.
