Non-parametric inference — the sign test and its confidence interval

Let $X_1,X_2,…,X_7$ be a random sample drawn from a continuous distribution with unknown unique median $M$. The null hypothesis $H_0:M=2$ is tested against the alternative $H_1:M>2$ at level of significance 0.05 using the right-tailed test based on the Sign test statistic $K$, which is the number of observations in the sample greater than 2. If the observed sample is $-3,-6,1,9,4,10,12$, which of the following statements are true?
