The average weight of a package of rolled oats is supposed to be at least 16 ounces. A sample of 18 packages shows a mean of 15.95 ounces with a standard deviation of .44 ounce.

(a) At the 5 percent level of significance, is the true mean smaller than the specification? Clearly state your hypotheses and decision rule.

a. H₀: μ ≥ 16. Reject H₀ if t_calc > -1.740b.H₁: μ < 16. Reject H₁ if t_calc < -1.740c.H₀: μ ≥ 16. Reject H₀ if t_calc < -1.740d.H₁: μ < 16. Reject H₁ if t_calc > -1.740   abcd 

(b) If α = .010, we would have

a. failed to reject the null hypothesis.b.rejected the null hypothesis. ab 

(c)Use Excel to find the p-value. (Round your answer to 4 decimal places.)
