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) \( p \)-value = 0.005

(b) \( p \)-value = 0.010

(c) \( p \)-value = 0.015

(d) \( p \)-value = 0.020

(e) \( p \)-value = 0.025
