Bags of a certain brand of tortilla chips claim to have a net weight of 14 ounces. Net weights actually vary slightly from bag to bag. Assume net weights are Normally distributed. A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised and so intends to test the hypotheses H0: μ = 14 versus Ha: μ < 14. To do this, he selects 16 bags of tortilla chips of this brand at random and determines the net weight of each. He finds a sample mean of 13.88 ounces with a standard deviation of s = 0.24 ounces. Determine which of the following statements is true, regarding the decision the representative would make.

a.) He would reject H0 at a significance level of 0.05 but not at 0.025.
b.) He would reject H0 at a significance level of 0.025 but not at 0.01.
c.) He would not reject H0 at a significance level of 0.05.
d.) He would reject H0 at a significance level of 0.01.
