We find the CP-violating phase to be within the range beta(J/psi phi)(s) is an element of [0.02, 0.52] boolean OR [1.08, 1.55] at 68% confidence level where the coverage property of the quoted interval is guaranteed using a frequentist statistical analysis. This result is in agreement with the standard model expectation at the level of about one Gaussian standard deviation.
