18. Suppose we want to test the hypothesis of \( H_0 : \mu \geq 1 \) versus \( H_a : \mu < 1 \), and a random sample of \( n = 49 \) gives mean \( \bar{x} = -1 \) and standard deviation \( s = 6.4516 \). What is the \( p \)-value of the test?

(a) \( p\text{-value} = 0.005 \)

(b) \( p\text{-value} = 0.010 \)

(c) \( p\text{-value} = 0.015 \)

(d) \( p\text{-value} = 0.020 \)

(e) \( p\text{-value} = 0.025 \)
