P-value of one-sided t-test

Let X1,X2,…,X9X_1, X_2, \dots, X_9 be a random sample from a N(μ,σ2)N(\mu, \sigma^2) distribution, where μ∈R\mu\in\mathbb{R} and σ>0\sigma > 0 are unknown. Let the observed values of Xˉ=19∑i=19Xi\bar{X}=\frac{1}{9}\sum_{i=1}^9 X_i and S2=18∑i=19(Xi−Xˉ)2S^2 = \frac{1}{8}\sum_{i=1}^9 (X_i - \bar{X})^2 be 9.89.8 and 1.441.44, respectively. If the likelihood ratio test is used to test the hypothesis H0:μ=8.8H_0: \mu=8.8 against H1:μ>8.8H_1: \mu > 8.8, then the pp-value of the test equals __________ (round off to 33 decimal places)
