At 5% level of significance, is true mean smaller than specification? Clearly mention your hypotheses and decision rule.

H₀: μ ≥ 18, reject H₀ if t < -1.74

H₁: μ < 18, reject H₁ if t > -1.74

H₀: μ ≥ 18, reject H₀ if t > -1.74

H₁: μ < 18, reject H₁ if t < -1.74

Requirement 2:

Determine the p-value.
