Let 𝑥1, 𝑥2, 𝑥3 and 𝑥4 be observed values of a random sample from an 𝑁(𝜃, 𝜎 2 ) distribution, where 𝜃∈ℝ and 𝜎>0 are unknown parameters. Suppose that 𝑥̅=\(\frac{1}{4} ∑^4_{i=1} 𝑥_𝑖 = 3.6 \) and \(\frac{1}{3} ∑^4_{i=1} (𝑥_𝑖-\overline{x} )^2= 20.25\) . For testing the null hypothesis 𝐻0 ∶ 𝜃=0 against 𝐻1 ∶𝜃≠0, the 𝑝-value of the likelihood ratio test equals
